CHARACTER

xylene, usually refers to a mixture of three isomers of p-xylene, o-xylene and m-xylene, with a chemical formula of C8H10 and a molecular weight of 106.17. Xylene is a colorless transparent liquid with aromatic odor, which is an important chemical raw material. It is mainly used in the production of coatings, resins, dyes, pesticides and pharmaceutical intermediates. In the coating industry, xylene is used as a solvent to improve the adhesion and gloss of coatings; in the resin industry, it is the raw material for the synthesis of unsaturated polyester resins; in the dye industry, xylene is used to produce a variety of organic dyes; In addition, xylene is also used in the production of pesticides, herbicides, pharmaceutical synthesis intermediates, etc. As a multi-purpose chemical raw material, xylene has a wide range of applications in the national economy.

APPLICATIONS

(1) Production of phthalic anhydride and derivatives: o-xylene is the main raw material for the production of phthalic anhydride. Phthalic anhydride can be used to manufacture plasticizers, alkyd resins, unsaturated polyesters, etc. These products are widely used in plastics, paints, coatings, radar radomes, aircraft parts, automobile shells and other building materials and chemical equipment.

(2) the field of medicine: o-xylene has an important use in the field of medicine, can be used as a raw material for the synthesis of drugs, such as vitamins, aspirin, aminopyrine and other drugs. In addition, it can also be used as a solvent for drug delivery systems, and plays a role in dissolving and solubilizing some drugs in oral formulations.

(3) Pesticides and plant growth regulators: o-xylene can be used in the manufacture of pesticides and fungicides, as well as plant growth regulators, which contribute to agricultural plant protection and plant growth, and increase crop yields.

(4) Organic solvents and extractants: o-xylene has good solvent properties and can dissolve many organic substances that are not easily dissolved in water, so it is widely used in the manufacture of adhesives, lubricants, resins, plastics, rubber and other industrial products. At the same time, it can also be used as an extraction agent in the oil refining process, used to extract benzene, toluene, xylene and other substances in the aromatic mixture.

(5) Cosmetics and personal care products: O-xylene is widely used in cosmetics and personal care products due to its unique aroma, such as perfume, soap, shampoo, shower gel, etc., which can not only add the aroma of the product, but also Improve the stability and texture of the product.

(6) Aviation gasoline additives: O-xylene can also be used as an additive for aviation gasoline, which helps to improve fuel performance and efficiency.

(7) Other uses: In addition, o-xylene can also be used in the manufacture of dyes, pigments and photosensitive materials, used as plasticizers and dispersants in coatings and inks, and as cleaning agents for electronic products.
