Xylene (dimethylbenzene) as a colorless liquid; two hydrogens on the benzene ring is substituted with methyl product of industrial grade xylene, presence o, m, of three isomers in the industry, referring to the above-mentioned xylene a mixture of isomers. Xylene with a pungent odor, flammability, and ethanol, chloroform or ether can be any mix, insoluble in water. A boiling point of 137 ~ 140 ℃. Xylene and low toxicity, the US Conference of Governmental Industrial Hygienists (ACGIH) would be classified as A4 level, namely the lack of substance to humans, animals, evidence of carcinogenicity. Xylene pollution mainly from synthetic fibers, plastics, fuel, rubber, and various paint additives and various adhesives, waterproof material, but also the combustion gases from fuel and tobacco. Chinese name xylene English dimethylbenzene; xylene chemical formula C8H10 molecular weight of o-xylene 106.17CAS accession number: 95-47-6, m-xylene: 108-38-3, p-xylene: 106-42-3 o-xylene Melting point: -25.2 ℃ industrial grade xylene prices, m-xylene: -47.9 ℃, xylene: 13.2 ℃ boiling point of o-xylene: 144.43 ℃, m-xylene: 139.12 ℃, xylene: 138.36 ℃. Water-soluble insoluble in water, soluble in alcohol and ether. Density relative density of about 0.86 Xylene is a colorless, transparent appearance of liquid sources of pollution xylene is an important chemical raw material industrial grade xylene delivery, organic synthesis, synthetic rubber, paints and dyes, synthetic fibers, petroleum processing, pharmaceuticals, fiber factors such as production plant effluents, as well as the production equipment is not enclosed and workshop for ventilation, is a major source of environmental xylene. Transportation, storage overturned in the process, spills, fires will cause accidental pollution incidents. 1. mainly used as chemical raw materials and solvents. It can be used in the production of phthalic anhydride; dyes; pesticides and industrial grade xylene pharmaceutical manufacturers, such as vitamins. It can also be used for aviation gasoline additive. 2 as a solvent, but also for the manufacture of phthalic anhydride, phthalonitrile, xylene, xylenol and amine starting materials, aviation gasoline additive. 3. mainly used as a solvent and for the synthesis of paints, coatings.
