Method of decomposing an alkyl chloroformate.

摘要

A chloroformic acid alkyl ester is decomposed to a corresponding alkyl chloride by bringing a gas containing the chloroformic acid alkyl ester into contact with a catalyst comprising an activated carbon and/or an inorganic oxide, for example, alumina, silica-alumina, synthetic zeolite, natorolite, mordenite, silica, titania or zirconia, the chloroformic acid alkyl ester-containing gas being, for example, a reaction product mixture derived from a gas phase catalytic carbonylation reaction of carbon monoxide with at least a nitrous acid ester in the presence of a solid catalyst and a chlorine-containing substance, for example, hydrogen chloride.
