Abstract
Triphosgene has rapidly emerged as an important green chemical product in recent years.It is synthesized by photo-catalyzed chlorination of dimethyl carbonate.Two synthetic technologies are employed in commercial production:solvent technology using tetrachloromethane as solvent,and no solvent technology only using dimethyl carbonate itself.It is an ideal substitute for high toxic phosgene which has widely used in chemical industry,and it can react with alcohols,amines,carboxylic acids,aldehydes,amides,etc.to prepare many important organic compounds and chemical materials.The application in chemical industry,such as to prepare organic compounds,pharmaceuticals,agricultural chemicals,synthetic dyestuffs,polymer materials and etc.will developed more and more rapidly in the future.
