Xylene CAS 1330 207
Xylene, chemical formula C8H10, is the product of the substitution of two hydrogens on the benzene ring by methyl groups, there are three isomers: orthoxylene (CAS number 95 -47-6), orthoxylene (CAS number 108 -38-3), paraxylene (CAS number 106 -42-3). In industry, xylene refers to a mixture of these isomers.
Widely used in coating, resin, dye, ink and other industries as solvent; Used in medicine, explosives, pesticides and other industries as synthetic monomer or solvent; It can also be used as a high-octane gas oline component and is an important raw material for organic chemical industry. It can also be used to remove asphalt from the car body. The pathology department of the hospital is mainly used for the transparency and dewaxing of tissues and sections.
Industrial o-xylene as raw material, first washed with industrial concentrated sulfuric acid until the acid layer is colorless, and then washed with 10% sodium hyd roxide solution and water in turn to qualify, dried with anhydrous calcium chloride after separating the water layer, and then rectification, after the distillate is clear, collect the middle fraction, that is, pure product.
