| 摘 要： | 以橡胶籽油(RSO)为原料,采用非均相介孔分子筛催化剂Ti-SBA-15催化制备环氧橡胶籽油(ERSO),探讨了催化剂用量、氧化剂叔丁基过氧化氢(TBHP)用量、反应时间、反应温度等因素对环氧化反应的影响。结果表明,Ti-SBA-15介孔分子筛催化剂催化制备ERSO的最佳工艺条件为:催化剂Ti-SBA-15用量0.062%(摩尔分数,以RSO物质的量计),TBHP与RSO物质的量比为1.3:1,反应时间6 h,反应温度70℃,此条件下制备的ERSO环氧值为68.9 mmol/g,产物转化率为82.22%,双键转化率为69.93%。通过FT-IR对比分析,进一步证实了环氧基团的生成。

| Abstract: | Epoxided rubber seed oil (ERSO) was prepared from rubber seed oil (RSO) by using heterogeneous mesoporous molecular sieve Ti-SBA-15 as catalyst. The influences of catalyst dosage, the oxidant tert-butyl hydroperoxide (TBHP), reaction time and reaction temperature on the epoxidation of RSO were discussed. Results showed that the ERSO with epoxy value of 68.9 mmol/g was obtained with the dosage of RSO 0.062% (mole fraction, based on the mole value of RSO), the molar ratio for TBHP to RSO 1.3:1, reaction time 6 h and reaction temperature 70℃. Under these optimal conditions, the RSO conversion was 82.22%, and the conversion of double bond was 69.93%. Furthermore, the formation of epoxy group was confirmed by FT-IR. |
