摘要 以一氯化硫和异丁基硫醇为原料,石油醚作溶剂,在0-4℃下反应45 h,合成了二异丁基四硫,选取最佳 反应摩尔比(异丁基硫酸:氯化硫)为3,产率达到86.0%;通过液相色谱、核磁共振谱、红外光谱证实了其结构. Diisobutyl tetrasulfide was prepared by sulfur monochloride with isobutyl mercaptan in petroleum ether at 0 - 4℃. The reaction was 4.5 h ,the optimum molar ratio of isobutyl mercaptan to sulfur monochloride was 3 and the yield of the product amounted to 86.0%. The structure of product was confirmed by IR, 1HNMR and liquid chromatograph.
