氯化汞触媒是以分析纯氯化汞为活性物质,ZZ30活性炭为载体,用浸渍法生产的,作电石乙炔法氯乙烯合成工业用催化剂。但是,目前我国各聚氯乙烯生产厂,在制造单体合成用的氯化汞触媒过程中,一般都采用碘量法以控制氯化汞溶液中的氯化汞含量,经活性炭吸附后残液中尚存的氯化汞含量,以权衡吸附是否完全,至于氯化汞触媒中氯化汞的真实含量,以及使用一段时间后废、旧氯化汞触媒中氯化汞含量究竟还有多少?由于缺
Mercury chloride catalyst is pure mercury chloride as the active material, ZZ30 activated carbon as a carrier, produced by the impregnation method for the synthesis of calcium chloride acetylene catalyst for industrial use. However, at present, PVC production plants in our country generally use iodometry to control mercuric chloride content in the mercuric chloride solution during the process of manufacturing mercuric chloride catalyst for monomer synthesis. In the remaining mercury chloride content in order to balance the adsorption is complete, as the mercuric chloride catalyst, the actual content of mercury chloride, as well as the use of waste after a period of time, the old mercuric chloride catalyst mercuric chloride content actually how much? Due to lack of
