Product Description of Mix Xylene CAS#1330-20-7
Xylene (dimethylbenzene) is a colorless, transparent aromatic liquid formed by the substitution of two hydrogen atoms on the benzene ring with methyl groups. It has a boiling point of 137–140°C.
Xylene exists in three isomeric forms—o-xylene, m-xylene, and p-xylene—depending on the relative positions of the methyl groups. In industrial applications, “xylene” typically refers to a mixture of these isomers along with ethylbenzene. Product grades are generally classified as superior or first-class, based on distillation ranges such as 3°C and 5°C.
The product is miscible with ethanol, chloroform, and ether, but insoluble in water. It is widely used as an organic solvent in industries such as pharmaceuticals, coatings, resins, dyes, explosives, and pesticides.
Xylene is moderately toxic and has a certain degree of carcinogenic risk. Environmental exposure may arise from sources such as synthetic fibers, plastics, fuels, rubber, coating additives, adhesives, waterproof materials, as well as combustion emissions from fuels and tobacco.

Product Application of Mix Xylene CAS#1330-20-7
Mix xylene is widely used as a solvent and for the determination of water content in various organic compounds, as well as a cleaning agent for microscopes.
It is also applied as a cleaning agent for silicon components and thermistors, providing effective removal of contaminants in electronic and precision applications.
Mixed xylene consists of o-xylene, m-xylene, p-xylene, and ethylbenzene. When used as a chemical raw material, the individual isomers can be separated prior to further processing.
The product is primarily used as a solvent for paints and coatings, and also serves as an additive in aviation gasoline, supporting improved performance in fuel formulations.
