中文摘要:
      研究异丙基黄原酸酯多硫化物的合成工艺,探讨各个反应阶段的物料配比、反应温度和反应时间等对产品收率的影响。试验得出的合成异丙基黄原酸钠的最佳工艺条件为:用甲苯作溶剂,n(异丙醇)∶n(二硫化碳)∶n(氢氧化钠)=1∶0.95∶0.90,反应温度10~15 ℃,反应时间12~14 h;合成异丙基黄原酸酯:n(异丙基黄原酸钠)∶n(双氧水)=1.0∶0.60,双氧水滴加时间5~6 h,反应温度25~30 ℃,保温时间50~60 min;合成异丙基黄原酸酯多硫化物的最佳工艺条件为:n(异丙基黄原酸酯)∶n(硫黄)=1.0∶2.0,反应温度80~90 ℃。
英文摘要:
      The synthesis process of isopropyl xanthogen polysulfide was investigated in this study, and the influence of the raw material ratio, reaction temperature and reaction time of each reaction stage on the production yield was discussed. Based on the experimental results the optimum synthesis conditions for each stage were obtained. In the synthesis of sodium isopropyl xanthate, toluene was used as solvent, the molar ratio of isopropanol, carbon disulfide and NaOH was 1.00∶0.95∶0.90, the reaction temperature was in the range of 10 ~ 15 ℃, and the reaction time was 12 ~ 14 h. In the synthesis of isopropyl xanthate ester, the molar ratio of sodium isopropyl xanthate and hydrogen peroxide was 1.00∶0.60, the hydrogen peroxide was added during a period of 5 ~ 6 h, the reaction temperature was maintained at 25 ~ 30 ℃, and the reaction was completed about 50 ~ 60 min after the addition of hydrogen peroxide. In the synthesis of isopropyl xanthate polysulfide, the molar ratio of isopropyl xanthate ester and sulfur was 1.0:2.0 and the reaction temperature was 80 ~ 90 ℃.
