Xylenes
Product Description:
Xylene, with the chemical formula C8H10, is a product in which two hydrogens on the benzene ring are replaced by methyl groups. There are three isomers, ortho, meta, and para. They are ortho-xylene (CAS No. 95-47-6), Meta-Xylene (CAS No. 108-38-3), Para-Xylene, (CAS No. 106-42-3). In industry, xylene refers to the mixture of the above isomers.
Colorless transparent liquid. Has a special smell of aromatic hydrocarbons. It is a mixture of three isomers consisting of 45%-70% m-xylene, 15%-25% p-xylene and 10%-15% o-xylene. It is easy to flow and can be mixed with absolute ethanol and ether Miscible with many other organic solvents.
Xylene has a pungent smell, is flammable, can be mixed with ethanol, chloroform or ether, and is insoluble in water. The boiling point is 137-140°C.

Application：
It is widely used as a solvent in coatings, resins, dyes, inks and other industries; it is used as a synthetic monomer or solvent in medicine, explosives, pesticides and other industries; it can also be used as a component of high-octane gasoline, and is an important raw material for organic chemicals. It can also be used to remove asphalt from car bodies. The pathology department of the hospital is mainly used for the transparent and dewaxing of tissues and slices.
