Application
It is used to synthesize chloroformates, isocyanates, polycarbonates and acyl chloride.

Triphosgene, also known as di(trichloromethyl)carbonate, is an organic compound with the chemical formula C3Cl6O3, a white crystalline powder that decomposes slightly at the boiling point to produce trichloromethyl chloroformate and phosgene, mainly used in the synthesis of chloroformate, isocyanate, polycarbonate and chloroformyl chloride, etc. It is widely used as an intermediate in plastics, pharmaceuticals, herbicides and pesticides.

It is used in the synthesis of chloroformate, isocyanate, polycarbonate and chloride, etc. Solid phosgene, also known as triphosgene, is synthesized from dimethyl carbonate – a green chemical material, which is highly reactive and can replace phosgene in various chemical reactions, and the main types of reactions it can be involved in are: chloromethylation, carbonic acid esterification, urelation, isocyanate esterification, chlorination, isonitriles, ring formation reactions, alpha-chlorination of aldehydes Formylation, oxidation of alcohols, etc. In organic synthesis, solid phosgene can replace oxalyl chloride as an activator of dimethyl sulfoxide in the oxidation reaction of alcohols and be used conveniently and safely in the preparation of hydroxyl compounds; solid phosgene can also change different types of alcohols into the corresponding chlorinated compounds. In the pharmaceutical industry, solid phosgene can replace phosgene in the synthesis of a large number of pharmaceutical.
