o-Xylene (Ortho-Xylene) is an aromatic hydrocarbon with the formula C6H4 (CH3) 2, which is mainly extracted from crude oil. Ortho-Xylene is the same xylene with methyl groups in its 1 and 2 positions. Xylene is a colorless and flammable liquid with a sweet smell that exists in the form of 3 isomers of Meta, Ortho, and Para-Xylene. o-Xylene is the second functional isomer of xylene used to make PVC plastic. Industrial xylene is not only used as a solvent and additive in the rubber and coatings industry, but also as an additive in aviation fuel.

The Ortho, Meta, and Para-Xylene isomers isolated from this compound are phthalic acid, isophthalic acid, and terephthalate acid, respectively. Phthalic acid and terephthalic acid are used in the production of plastics, polyester resins, and polyester fibers.

Petroleum contains about 1% xylene, and most Ortho-Xylene is produced by petroleum cracking. The net production of this material in 2019 was about 500,000 tons.

o-Xylene is originally produced from coal, but currently, most of its domestic and foreign production is mainly done through modified catalytic extraction of oil and the thermal cracking of aromatic hydrocarbons.

Applications of o-Xylene

o-Xylene is the second commercial isomer of xylene, and almost all of it is used in the manufacture of phthalic anhydride (PA), which has three main uses, including the use in the manufacture of polyvinyl chloride (PVC) resins, the production of unsaturated polyester resins (UPRs). and making alkyl resins that are used for surface coatings.

Ortho-Xylene in industrial xylene has a difference of more than 5.2 degrees Celsius from other isomers, and this substance can be obtained with a purity of 95% by careful distillation. Its further processing using sulfonation and distillation for purification can give us a substance with greater purity.

This compound is an inexpensive raw material for the production of phthalic anhydride, which has a high yield potential and is used as a precursor to many products, drugs, and other chemicals.

This compound is mainly used as a chemical raw material and solvent, and it can be used to produce dyes, pesticides, drugs, vitamins, and as chromatography standards.

Chlorine white powder has 33.5% to 39% chlorine, and calcium hypochlorite granules or powdered chlorine has 65 to 70% chlorine by weight.

What is calcium hypochlorite?

Calcium hypochlorite is an inorganic compound with the formula Ca(OCl)2. This material is the main active ingredient of commercial products called bleaching powder, chlorine powder, or chlorine lime, which is used for water purification and as a bleaching agent. This compound is relatively stable and has more available chlorine than sodium hypochlorite (liquid bleach). Its appearance is a white solid. Due to its slow decomposition in humid air, it smells strongly of chlorine.

In chemistry, hypochlorite is the anion with the chemical formula ClO2. It combines with several cations to form hypochlorites, which may also be considered salts of hypochlorous acid. Common examples include sodium hypochlorite (a dishwashing liquid or household bleach) and calcium hypochlorite (except bleaching powder, swimming pool “chlorine”).

Peracetic acid, also called peroxyacetic acid or PAA, is an organic compound with the chemical formula CH3CO3H. This organic peroxide is a colorless liquid with a distinct pungent smell like vinegar, which is reminiscent of acetic acid and can be very corrosive. This material is a weaker acid than the parent acetic acid and its pKa is 8.2. Peracetic acid (C2H4O3) is a mixture of acetic acid (CH3COOH) and hydrogen peroxide (H2O2) in water.

Table of technical specifications of peroxyacetic acid

The production method of peracetic acid

Peracetic acid is produced industrially by the oxidation of acetaldehyde:

O₂ + CH₃CHO → CH₃CO₃H

This substance forms a strong acid when treating acetic acid with hydrogen peroxide with a catalyst:

H₂O₂ + CH₃CO₂H ⇌ CH₃CO₃H + H₂O

As another option, acetyl chloride and acetic anhydride can be used to produce an acid solution with lower water content. This material is produced by the reaction between hydrogen peroxide and acetic acid:

Acetic acid + hydrogen peroxide → peracetic acid

Peracetic acid can also be produced by the oxidation of acetaldehyde. This material is usually produced in concentrations of 15%.

When peracetic acid dissolves in water, it decomposes into hydrogen peroxide and acetic acid, which, as the water breaks down, oxygen and carbon dioxide lost. The degradation products of peracetic acid are non-toxic and can be easily dissolved in water. This material is a very strong oxidant that overestimates the oxidation potential of chlorine and chlorine dioxide.

Peracetic acid is also produced by some laundry detergents. This route involves the reaction of tetraacetylethylenediamine in the presence of an alkaline solution of hydrogen peroxide. This material is an effective and stronger bleaching agent than hydrogen peroxide itself. (PAA) also occurs naturally in the environment through a series of photochemical reactions involving formaldehyde and photo-oxidizing radicals.

This material is always sold as a mixture of acetic acid and hydrogen peroxide in a solution, to maintain its stability. The concentration of acid as an active ingredient can be different.

Xylene is a colorless, volatile, sweet-smelling, flammable liquid that is insoluble in water and remains on its surface when mixed with water. Xylene consists of two methyl groups attached to the six-carbon ring of benzene, therefore it is also called dimethylbenzene.

Features of xylene

The chemical and physical properties of xylene are different according to the respective isomers. The melting point of this compound varies from -47.87°C (m-Xylene) to 13.26°C (p-Xylene). Typically, the melting point of the para isomer is much higher because it easily fits into the crystal structure. The boiling point of each isomer is around 140°C (284°F).

The density of each isomer is about 0.87 g/ml, and as a result, it has a lower density than water. This chemical in the air can be identified by the smell in concentrations from 0.08 to 3.7 ppm, and in water with a concentration of 0.53 to 1.8 ppm, its sweet taste can be recognized.

Specific applications of xylene

Xylene, often called xylol, is a powerful chemical solvent. This substance is derived from petroleum and therefore has certain advantages over other similar products.

It may seem odd, but solvents are chemical composites that are molecularly similar to the substances they are designed to dissolve. Since xylene is made from petroleum, it is especially good at removing paints, wood stains, and other synthetic products without damaging surfaces. It also acts as a solvent with compounds used on metals to prevent rust. Other materials that xylene will dissolve include a variety of adhesives and putty, as well as grease, glazes, resins, and waterproofing materials.

Formic acid, ant essence or systematically methanoic acid, is the simplest carboxylic acid and has the chemical formula HCOOH. This substance is an important intermediate in chemical synthesis and is produced naturally. The word “formic” is derived from the Latin word for ant, formica, which indicates the distillation of the ant’s body. The ester, salt and anion of formic acid is called formate. Industrially, formic acid is produced from methanol.

History of formic acid

Some alchemists and naturalists knew that anthills gave off acid fumes as early as the 15th century. The first person to describe the isolation of this substance (by distillation of large numbers of ants) was the English naturalist John Ray in 1671. Ants secrete formic acid for attack and defense purposes.

Formic acid was first made by the French chemist Joseph Guy Lussac from hydrocyanic acid. In 1855, another French chemist, Marcelin Bertrelot, produced formic acid by synthesizing carbon monoxide.

Formic acid has long been considered a chemical compound of little interest in the chemical industry. By the late 1960s, significant quantities became available as a byproduct of acetic acid production. Now this substance has increased as a preservative and antibacterial agent in animal feed.

What is formic acid?

Formic acid is named after ants that have a high concentration of the compound in their venom. In ants, formic acid is derived from serine via an intermediate. Formic acid‘s conjugate base, formate, also occurs widely in nature. The method for measuring formic acid in body fluids, which is designed to determine formate after methanol poisoning, is based on the reaction of formate with bacterial formamide dehydrogenase.

Formic acid is flammable at a concentration of 85%. Formic acid contains 53 grams per liter of hydrogen at room temperature and atmospheric pressure, which is three and a half times what compressed hydrogen gas can achieve at a pressure of 350 bar. Pure formic acid is a liquid whose flash point is +69°C, much higher than that of gasoline (-40°C) or ethanol (+13°C).

Polyvinyl chloride, or PVC, is a universal polymer with many applications (pipes, floor coverings, cable insulation, bottles, packaging foils, medical products, etc.).

The reason for the widespread use of this polymer is its low cost, suitable physical and chemical properties, and good resistance to environmental conditions. In the following, we will discuss the properties, structure, production method, buing, applications, and other things about this polymer.

What is polyvinyl chloride?

Polyvinyl chloride, or PVC, is a thermoplastic polymer with strength, stiffness, and good resistance to corrosion and chemicals. This product is initially produced as a white powder, and additional processes are performed based on the type of use expected from it. For example, in cases where flexibility is needed, a plasticizer should be added to it. It is a fragile white compound produced in two complex and flexible types during production in its pure state and without additives. This substance is a combination of crude oil derivatives and chlorine gas produced during the polymerization process.

The term bitumen refers to a viscous, non-crystalline, black or dark brown substance that can be dissolved in organic solutions, such as toluene and carbon disulfide, and has adhesive and waterproof properties.

This substance is generally composed of hydrocarbons, which usually contain 80% carbon and 15% hydrogen. Other residues in this viscous material include oxygen, sulfur, nitrogen, and various metals. Bitumen can be obtained from various sources and occurs naturally. The amount of this material in crude oil may vary, but the more normal range is between 25% and 40%, while the usual range is 15% to 80%.

Broad classification for crude oils

• Bitumen base
• Paraffin base
• Bitumen and paraffin base

Depending on the type of crude oil, bitumen exists either as a colloidal dispersion or in a solid state. During the refinement process, the oil-to-particle ratio changes as petroleum oils are removed by distillation. Instead of these particles being scattered and relatively few in number, they are getting closer to each other and increasing in size.

Typically, oil tar is a colloidal dispersion of black solids (hydrocarbons) at the end of the distillation process. There is also a yellow-brown petroleum liquid known as the melted fraction in which asphaltenes are dispersed. Also, to be present in asphaltenes as a stabilizing agent, another group of hydrocarbons are known as resins.

This substance is found in nature in many forms, from the hard, easily crushed bitumen found in rock asphalt to the softer, more viscous material found in oil sands and so-called asphalt lakes. This material is usually mixed with various proportions of mineral or vegetable impurities that must be extracted before use, and is effectively used as an engineering material.
It may also be found as asphaltite, natural bitumen without various impurities in solution in carbon disulfide. Natural bitumen, like petroleum, occurs as a result of the specific breakdown of marine debris. This occurs over thousands of years through porous rocks such as limestone or sandstone, often transported by volcanic action.

Separation of bitumen and tar coal is important. Although coal tar is black and sticky like this material, it is derived from the carbon of coal and therefore has very different chemical properties.

Engineering projects everywhere in the world, from the construction of transcontinental highways to the waterproofing of flat roof surfaces, rely on the special properties of bitumen. Crude oil processed by the oil industry provides a small percentage of this vital substance.

Polyamide, commonly known as nylon, is a thermoplastic polymer introduced to the industry in the mid-1930s by DuPont engineers.

Since then, polyamide has been a suitable material in most industries, such as automobile manufacturing, the food industry, sports equipment, the carpet industry, and most importantly, the textile and clothing industry.

Polyamides are usually converted into fibers to be used. If you are willing to get familiar with the types of simple polyamide available in the industry, their characteristics, and their use, this article will help you.

What is polyamide?

Simple polyamide is a polymer that includes amide groups (R-CO-NH-R) as an essential part of the polymer chain. These amide groups keep repeating. A simple polyamide with a high molecular weight is usually called nylon.

Simple polyamide is a crystalline polymer formed from the combination of a diacid and a diamine. In the mixture of these two monomers, the linking of molecules takes place through the formation of amide groups. The most crucial simple polyamide is nylon, which is considered a very flexible material. Today, simple polyamide is produced in the form of thin and long threads.

At first, simple polyamide was used to make parachutes and ropes in World War II, but later in the 40s, it gained its place in the clothing and fabric market. Due to its elasticity, this material achieved great success in the hosiery industry and quickly replaced silk stockings, which were expensive and less flexible.

Today, simple polyamide is used for many sticky clothes, such as women’s socks, pantyhose, swimwear, underwear, and high-quality and comfortable sports clothes.

Lubecut is one of the derivatives of crude oil and is one of the cuts of the distillation tower of oil refineries. Lubecut has two types, heavy and light, each used in the oil industry.

According to experts, only a good lubricant (oil, grease, etc.) can guarantee the optimal operation of machine equipment. About 55% of premature equipment failures are due to inappropriate lubricants in the industry. Lubricants are substances used to reduce friction and prevent the wear of moving metal parts in contact with each other.

This article will discuss lube cuts, the main component, and raw materials for motor oil production.

What is a lube cut?

lubecut is the main component and raw material for producing motor oil, which makes up about 85-95% of it. Usually, by refining crude oil, only a few percent of hydrocarbon materials with atomic numbers between 20 and 50 are obtained, which are suitable for use as lubricants. It is one of the oil cuts (products) called oil cut or lube cut. This cut is actually the oil refinery feed.

Lubecut is converted into oil from crude oil refineries then in the oil refineries, the refining operation is performed on the lubecut. Finally, a substance called base oil, the main ingredient of motor, industrial, and grease oils, is prepared from it.

As mentioned, the base oil is produced from lubecut. Basically, lubricants consist of two components: base oil and additives. After adding additives to the base oil, the final lubricant is obtained.

The process of obtaining lubecut

Production of base oil from lubecut by performing the refining process, in addition to separating non-hydrocarbon compounds, hydrocarbon compounds are also divided according to their boiling point, which is derived from the number of carbon atoms in their molecules. Usually, by refining crude oil, only a few percent of hydrocarbon materials with atomic numbers between 20 and 50 are formed, which are suitable for use as lubricants. It should be noted that the type and degree of viscosity of the base oil obtained depend on the lubecut input to the oil refinery. Therefore, to produce different base oils, it is necessary to use different lubecut.

Benzalkonium chloride is a type of cationic surfactant that is considered a non-oxidative biocide. This biocide is based on quateary ammonium compounds, which are effective even in low concentrations.

This biocide is soluble in water and is effective in preventing the activity of some vital bacterial enzymes (enzymes involved in glycolysis respiration), as well as releasing the contents of the bacteria into the environment. By increasing the contact time and concentration of the biocide, compounds containing nitrogen and phosphorus in the bacterial cell enter the surrounding environment, and thus the bacteria are destroyed. This material has the property of dispersing, spreading, and destroying sludge and algae.

Using this biocide may cause foaming. In order to make this biocide more effective, it is recommended to use it together with non-oxidizing isothiazolinone biocide.

This biocide can be used in all open or closed-circuit cooling and cooling systems, firefighting systems, ponds and pools, water transmission lines, etc.

Equipment and containers should be made of stainless steel, 316 steel, 304 steel, polypropylene, polyethylene, PVC, or Teflon.

Benzalkonium chloride (BAC, BAK, BKC, BZK), known as alkylidene methyl benzyl ammonium chloride (ADBAC), is a type of cationic surfactant. It is an organic salt classified as a quateary ammonium compound. ADBACs are used in three main categories: as a biocide, cationic surfactant, and phase transfer agent. methylammonium.

Solubility and physical properties of benzalkonium chloride

Depending on the purity, benzalkonium chloride ranges from colorless to pale yellow (impure). Benzalkonium chloride is easily soluble in ethanol and acetone, but its solubility is slower in water. Its aqueous solutions should be neutral to slightly alkaline. Concentrated solutions have a bitter taste and a faint smell like almonds. Standard concentrates are produced as 50% and 80% by-weight solutions. A 50% solution is completely blue.

Other names of dimethyl benzalkonium chloride

Benzalkonium chlorides (BACs), also known as alkyl dimethyl benzyl ammonium chlorides, quateary alkyl dimethyl (phenylmethyl) ammonium chlorides, quartz disinfectants, BACs, benzalkonium chlorides, and QACs.

Properties of dimethyl benzalkonium chloride

Benzalkonium chlorides (BAC) due to their broad-spectrum antimicrobial properties against bacteria, fungi, and viruses. Benzalkonium chloride is a broad-spectrum quateary ammonium antibacterial agent. This material is cationically charged and creates an antibacterial effect by absorbing the negatively charged bacterial membrane.

Gram-positive bacteria are generally more sensitive than gram-negative bacteria. Its activity depends on the concentration of surfactant and also on the concentration of bacteria at the moment of injection. Activity is largely unaffected by pH but increases significantly at higher temperatures and longer exposure times.
