| 中文摘要: |
| 以自制蓖麻酸甲酯为原料，对其进行了水解反应性能的研究。采用单因素试验考察了反应温度、水与蓖麻酸甲酯体积比、酸碱性及反应时间对蓖麻酸甲酯水解率的影响。结果表明：按碱性、中性、酸性水解顺序蓖麻酸甲酯水解率依次减小；反应温度越低，蓖麻酸甲酯水解率越小；水与蓖麻酸甲酯体积比越小，蓖麻酸甲酯水解率越小；反应时间缩短，蓖麻酸甲酯水解率减小；在酸性介质、水与蓖麻酸甲酯体积比1∶1、反应温度25?℃、反应时间60 min条件下，蓖麻酸甲酯水解率为4.2%。选择在酸性介质、较低温度、较少水量条件下对蓖麻酸甲酯进行快速水洗对降低其水解损失是有利的。 |
| 英文摘要: |
| With self-made methyl ricinoleate as raw material, the hydrolysis reaction properties of methyl ricinoleate were studied. The effects of reaction temperature, volume ratio of water to methyl ricinoleate, acidity and basicity and reaction time on the hydrolysis rate of methyl ricinoleate were investigated by single factor experiment. The results showed that the hydrolysis rate of methyl ricinoleate decreased in the order of alkaline, neutral and acidic hydrolysis. The lower the reaction temperature, the lower the hydrolysis rate of methyl ricinoleate. The smaller the volume ratio of water to methyl ricinoleate, the lower the hydrolysis rate of methyl ricinoleate. The hydrolysis rate of methyl ricinoleate decreased with the reaction time shortening. Under the conditions of acidic medium, volume ratio of water to methyl ricinoleate 1∶?1, reaction temperature 25?℃ and reaction time 60 min, the hydrolysis rate of methyl ricinoleate was 4.2%. It was advantageous for the washing of methyl ricinoleate under conditions of acidic medium, lower temperature and less water to reduce its hydrolysis loss. |
