无水二价或三价金属三氯乙酸盐在真空中加热分解生成三氯乙酰氯已有若干研究,三氯乙酸在催化剂作用下生成三氯乙酰氯的研究到目前为止只有郭正谊的报告(Mn~(2+)作催化剂),最近,我们发现,碱金属、碱土金属的阳离子对三氯乙酸分解生成三氯乙酰氯有催化作用。
There are several studies on the thermal decomposition of anhydrous or trivalent metal trichloroacetates in vacuum to form trichloroacetyl chloride. The research on the production of trichloroacetyl chloride by trichloroacetic acid under the action of catalysts has so far been reported by Guo Zhengyi Recently, we found that the cations of alkali metals and alkaline earth metals catalyze the decomposition of trichloroacetic acid into trichloroacetyl chloride.
