Isophthaloyl dichloride

CAS: 99-63-8
Molecular Formula: C8H4Cl2O2
Molecular Weight: 203.0222
Product description:Colorless or light yellow crystal. 41 ℃ melting point, boiling point of 276 ℃. Soluble in ether, in water, alcohol decomposition.Have sulfoxide chloride and phosphorus pentachloride method, phosgene method, isophthalic acid dimethyl chlorination process, isophthalic acid chlorination process. More by phosgene method, usually in the presence of formamide is a catalyst for light gasification reaction. If you first make isophthalic acid into intermolecular anhydride, then the gasification reaction, light isophthalic formyl chloride itself double used as reaction solvent, the higher yield can be obtained.Can be used in the synthesis of aramid fiber, polyacrylate, high temperature resistant resins, dyes, pigments, pharmaceutical and pesticide etc.
