摘　　要：针对螯合剂N,N'-哌嗪二硫代氨基甲酸盐制备中反应时间长、收率低、反应不充分等不足,选用有机碱四甲基胍为催化剂,哌嗪、二硫化碳、氢氧化钾水溶液为原料,优化反应条件,形成一种N,N'-哌嗪二硫代氨基甲酸盐制备收率提高的方法,产品收率可达96%以上。The preparation of chelating agent N,N'-bis-(dithiocarbamate)piperazine has the problems of long reaction time,low yield and insufficient reaction.In order to solve these problems,a method for raising the yield of N,N'-bis-(dithiocarbamate)piperazine is proposed.In this method,the organic base tetramethylguanidine is used as a catalyst,and piperazine,carbon disulfide and potassium hydroxide solution are used as raw materials,and the product yield can reach more than 96%by optimizing the reaction conditions.
