【摘要】 以异丙醇为溶剂，异丙醇钧和二硫化碳反应生成异丙基黄原酸钠1．1未经纯化，向反应瓶中直接加入二氯乙酸甲酯，制得2，2-双-（异丙基黄原酸基）乙酸甲酯2.2经过浓硫酸催化，得1，3，4，6-四硫杂戊搭烯-2，5-二酮3．整个过程操作简便，产率较高，是制备1，3，4，6-四硫杂戊搭烯3的简便方法．更多还原

【Abstract】 Sodium isopropyldithio xanthate 1 was sythesized by the reaction of sodium isopropylate and carbon disulfide with isopropanol as the sovent. 1 was no purified and reacteelwith methyl dlichloracetate, methyl 2, 2 - bis - (o - isopropyl dithio xanthyl) acetate 2 wasformed as the result. Catalysed by coneentrated sulfuric acid, 1, 3, 4, 6 - tetrathiopentalene-2, 5 -dione 3 was prepared. The whole process was convrient and the yield of productwas high.更多还原
