摘　　要：用无水硫化钠、单质硫和二硫化碳制备四硫代碳酸钠(产率75%)。将二碘甲烷滴加到四硫代碳酸钠的乙醇溶液中,回流反应10h,得到了1,2,3,5,6-五硫环庚烷;确定最佳萃取溶剂是四氯化碳,并且反应操作简单,反应时间从48h缩短到12h,产品产率提高了8%(原文献为30%)。Sodium tetrathiocarbonate was prepared from anhydrous sodium sulfide, s ulfur and carbon disulfide at a yield of 75%.1,2,3,5,6-Pentathiepane was obtaine d by refluxing diiodomethane and tetrathiocarbonate for 10h. After optimization it’s found out that the optimum solvent was carbon tetrachloride, and the metho d was simple. The reaction time could be reduced from 48h to 12h, and the yield of the product was 8% higher than that reported in literature(30%).
