| 应用领域 | Uses: Used in organic synthesis、[HSDB]、Trichloroacetyl chloride can be used for the manufacture of the esters and the anhydrides of trichloroacetic acid.、Methods of Manufacturing: Acetyl chloride is prepared from trichloroacetic acid and various inorganic acid chlorides (e.g.、SOCl2、PCl3) or with P2O5 and HCl. More useful methods are the oxidation of tetrachloroethylene with fuming sulfuric acid、oxygen、or fuming nitric acid and sulfuric acid at 18-20 °C、or from the reaction of pentachloroethane and dry oxygen under UV light. It has been obtained in 37% yield from carbon tetrachloride and carbon monoxide in the presence of aluminum chloride at 200 °C and high pressure. The most common production method is the gas-phase、photochemical oxidation of tetrachloroethylene with oxygen. The reaction is initiated with UV light、with radioactive irradiation、or it is sensitized with chlorine or iodine.、General Manufacturing Information: Acetyl chloride、2、2-trichloro-: ACTIVE |
