Product Application of Mix Xylene CAS#1330-20-7
Solvent, determination of water content in many organic compounds, microscope cleaner. Cleaning agent for silicon components and thermistors. Mixed xylene is a mixture of o-, m-, and p-xylene and ethylbenzene. When used as a chemical raw material, the isomers can be separated in advance. The mixture is mainly used as a solvent for paints and coatings and an additive for aviation gasoline.
