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.

Xylene is a term used for the mixture of three isomers of xylene, i.e. Ortho-Xylene, Meta-Xylene, and Para-Xylene we have explained each one specifically in other articles.

This material is mainly used as a solvent and is used in the printing, rubber, and leather industries and can replace toluene in places where slower drying is required. This chemical is primarily a synthetic chemical. However, it occurs naturally in oil, and coal, and is produced during forest fires.

Xylene is an aromatic hydrocarbon widely used as a solvent in industry and medical technology. The chemical formula of this compound is C6 H4 (CH 3) 2. This compound is found in small amounts in jet fuel, gasoline, and cigarette smoke.

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.
