Products Description of Mix Xylene CAS#1330-20-7Xylene (dimethylbenzene) is a colorless, transparent, aromatic liquid. It is the product of two hydrogen atoms on the benzene ring being replaced by methyl atoms. It has a boiling point of 137-140°C. Xylene is divided into three isomers: o-xylene, m-xylene, and p-xylene according to the positions of the two methyl atoms. In industry, xylene refers to a mixture of the above isomers and ethylbenzene.
