Product Overview
Description
----Xylene----
This product is colorless transparent liquid. It has a special smell of aromatic hydrocarbons. It is a mixture of 45% ~ 70% m-xylene, 15% ~ 25% p-xylene and 10% ~ 15% o-xylene isomers. It is easy to flow and can be miscible with anhydrous ethanol, ether and many other organic solvents.
Xylene has pungent smell, flammable, and ethanol, chloroform or ether can be mixed arbitrarily, insoluble in water. The boiling point is 137 ~ 140℃. The U.S. Conference of Governmental Industrial Hygienists (ACGIH) classifies xylene as a low-toxic chemical that lacks evidence of carcinogenicity in humans and animals. Plastics, fuel, rubber, additives of various coatings and various adhesives, waterproof materials, but also from fuel and tobacco combustion gas.
Widely used in coating, resin, dye, ink and other industries to do solvent; Used in medicine, explosives, pesticides and other industries to do synthetic monomer or solvent; It can also be used as high octane gasoline component, which is an important raw material of organic chemical industry. It can also be used to remove asphalt from the car body. Hospital pathology department is mainly used for tissue and section transparency and dewaxing.
Industrial o-xylene as raw material, first with industrial concentrated sulfuric acid washing to the acid layer colorless, and then with 10% sodium hydroxide solution, water washing to qualify, separated water layer after drying with anhydrous calcium chloride, and then distillation, after distillate clear, collection of middle distillate, that is, pure products.
