    Alias: Bis(trichloromethyl)carbonate; solid phosgene; trichloromethyl carbonate; tricarbonyl chloride; Bis(trichloromethyl)carbonate; BTC
    CAS NO: 32315-10-9
    Structural formula:
    Physicochemical properties Properties: White or off-white crystal with similar photo-odor.
    Melting point: 79°C-81°C
    Boiling point: 205°C-206°C (partial decomposition)
    Density: 1.78g/cm3 is
    soluble in organic solvents such as ethanol, benzene, ether and dichloromethane. . It is decomposed in the case of hot water and alkali hydroxide, and it has no effect in cold water.
    Uses For the synthesis of chloroformate, isocyanate, polycarbonate and acid chloride; solid phosgene, also known as Bis (trichloromethyl) carbonate, synthetic raw material is dimethyl carbonate - a green chemical raw material, is a highly reactive substance, It can replace phosgene for various chemical reactions. The main types of reactions that can be involved are: chloromethylation, carbonation, urealation, isocyanation, chlorination, isonitrileization, ring formation, aldehyde α-chlorination Chloroformylation, oxidation of alcohol, and the like. In terms of organic synthesis, in the oxidation reaction of alcohol, solid phosgene can replace oxalyl chloride as an activator of dimethyl sulfoxide, which is convenient and safe for the preparation of hydroxy compounds; solid phosgene can also make different types of alcohols For the corresponding chloride. In the pharmaceutical industry, solid phosgene can replace phosgene to synthesize a large number of medicines.
