3、 Purpose:

It is a mixture of p-xylene, o-xylene, m-xylene and ethylbenzene, colorless and transparent liquid. It is widely used as organic solvent and raw material for synthetic medicine, coating, resin, dye, pesticide and so on.

4、 Precautions

This product is a flammable hazardous chemical. Pay attention to ventilation, fire prevention and cooling during use, transportation and storage to avoid safety accidents.

Typical Properties

Xylene is a colorless, transparent and aromatic liquid. It is the product of two hydrogen substituted by methyl on the benzene ring. The boiling point is 137 ~ 140 ℃. Xylene is divided into three isomers: o-xylene, m-xylene and p-xylene according to the different positions of the two methyl groups. In industry, xylene refers to the mixture of the above isomers and ethyl benzene. The grade is generally superior grade and first grade of purified water with distillation range of 3 ℃ and 5 ℃. It can be freely mixed with ethanol, chloroform or ether and is insoluble in water. It is widely used in organic solvents and synthetic medicine, coatings, resins, dyes, explosives and pesticides. Xylene is moderately toxic and carcinogenic. Xylene pollution mainly comes from synthetic fiber, plastic, fuel, rubber, additives of various coatings, adhesives and waterproof materials, as well as combustion gas of fuel and tobacco leaves.
