摘　　要：聚二硫二丙烷磺酸类结构在酸性电镀铜中作为加速剂而被广泛使用。本文开发一种聚二硫二丙烷磺酸钾的合成方法,以硫代乙酸钾和1,3-丙磺酸内酯为起始原料,先制备得到易于分离纯化的硫代乙酸(S-丙磺酸基)酯钾盐,然后该盐先后在氢氧化钾中水解和过氧化氢中氧化,最终得到聚二硫二丙烷磺酸钾。通过探索反应投料比、反应温度、反应时间等因素造成的影响,确定了最佳合成条件。该合成方法产率高,杂质少,操作简单。Bis-(potassium-sulfopropyl)disulfide is widely used as an accelerator for acid copper plating baths.A synthetic method for potassium bis-(potassium-sulfopropyl)disulfide was developed.Potassium^(3)-(acetylthio)propane-1-sulfonate,which was easily separated and purified,was synthesized from potassium thioacetate and 1,3-propanesultone and then converted to potassium bis-(potassium-sulfopropyl)disulfide in the hydrolysis process with potassium hydroxide and the oxidation process with hydrogen peroxide successively.According to the effects of reagent ratios,reaction time and temperature on the reaction,the optimum reaction conditions were determined.This method had the advantages of high yield,low impurity content,and simple operation.
