以5-甲氧基色胺为原料,在微反应器中制备美乐托宁,设计了3种合成方案,采用均匀设计法对反应工艺进行了优化。在原料配比,停留时间和反应温度一样的条件下,对3个反应系统的收率进行比较。确定了3#微反应合成系统合成美乐托宁的最优工艺条件:5-甲氧基色胺∶二氯甲烷质量体积比为5.0×10-4 mg/L,乙酸酐与5-甲氧基色胺摩尔比为4∶1?,反应段停留时间45?s,分离段停留时间5?s,合成过程仅需50?s?即可完成,收率为83.8%。而传统工业生产需5?h,收率仅为70.2%。利用微反应器合成美乐托宁极大的缩短了反应时间,且能直接得到产品,简化了操作,对美乐托宁的连续化工业生产具有重要意义。
- Abstract:
-
Melatonin was prepared in a microreactor with 5-metroxytryptamine as raw material. Three synthetic schemes were designed and compared under the same mixture ratio, residence time and reaction temperature. The reaction process in 3# microreactor was also optimized by the uniform design experimentation: the mass concentration of 5-methoxy and methylene chloride was 5.0×10-4 mg/L, the mole ratio of acetic anhydride and 5-methoxy was 4∶1, the residence time of the reaction stage was 45 s, and the residence time of the separation stage was 5 s. Compared with the traditional process, the synthesis process time shortened from 5 h to 50 s, and the yield of melatonin in the new microreactor rose from 70.2% to 83.82%. Melatonin could be easily obtained in the microreactor with simplified operation, which is meaningful for its continuous industrial production.
