摘　　要：针对螯合剂聚乙烯亚胺二硫代氨基甲酸盐合成中反应时间长、收率低、反应不充分等不足,选用4-二甲氨基吡啶、1-(3-二甲氨基丙基)-3-乙基碳二亚胺盐酸盐双催化剂,聚乙烯亚胺、氢氧化钠水溶液、二硫化碳为原料,优化反应条件,形成一种聚乙烯亚胺二硫代氨基甲酸盐双催化的绿色合成方法。A double-catalyzed green synthetic method of polyethyleneimine dithiocarbamate is presented by this paper,which can solve the deficiencies in the synthesis of the chelating agent polyethyleneimine dithiocarbamate,such as long reaction time,low yield and insufficient reaction.This method uses 4-dimethylaminopyridine,1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride as double catalysts,polyethyleneimine,aqueous sodium hydroxide solution,and carbon disulfide as raw materials and complete optimization of reaction conditions to synthesize products.
