| 中文摘要: |
| 以油酸钠为模型物，在相转移催化剂四丁基溴化铵催化下与环氧氯丙烷反应制备端环氧基油酸酯，探讨了油酸钠与环氧氯丙烷摩尔比、反应温度和反应时间的影响，产物用核磁共振氢谱（1H NMR）和碳谱（13C NMR）进行结构鉴定。结果表明:优化的反应条件为油酸钠与环氧氯丙烷摩尔比1∶?20、反应温度70?℃、反应时间8 h，优化条件下端环氧基油酸酯得率为96%；产物中成功引入端环氧基。将该优化的反应条件用于橡胶籽油皂脚制备端环氧基脂肪酸酯的反应中，并采用红外光谱（FTIR）对产物进行结构表征。结果表明：产物结构中引入了端环氧基的同时保留了脂肪酸酯结构中的双键，产物端环氧基脂肪酸酯得率为80%。 |
| 英文摘要: |
| The sodium oleate was used as a model compound to react with epichlorohydrin in the presence of phase transfer catalyst tetrabutyl ammonium bromide to prepare terminal epoxy oleate, the effects of meterial molar ratio, reaction temperature and reaction time on the reaction were discussed, and the structure of product was verified by 1H NMR and 13C NMR. The results demonstrated that the terminal epoxy group was succesfully introduced to the product, and the terminal epoxy oleate with yield of 96% was obtained under the optimal conditions of molar ratio of sodium oleate to epichlorohydrin 1∶?20, reaction temperature 70?℃, and reaction time 8 h. In addition, the terminal epoxy fatty acid ester from soapstock of rubber seed oil was prepared under the same conditions, the structure of product was analyzed by Fourier Transform Infrared Spectroscopy (FTIR). The results showed that the terminal epoxy group was introduced into the product structure while retaining the double bond in the fatty acid ester structure, and the terminal epoxy fatty acid ester yield was 80%. |
