摘要
介绍了苯乙烯、四氯化碳合成肉桂酸的基本生产原理,阐述了肉桂酸生产过程中的加成、水解、皂化工序的改进。通过改造水解乙酸回流和提高皂化反应pH值,使肉桂酸的生产收率由33 7%提高到52 8%。
The manufacture process of cinnamic acid from styrene and carbon tetrachloride was described. Improvements of the conditions for addition,hydrolysis and saponification in the process of cinnamic acid were made.After the improvements,the yield of cinnamic acid was raised to 528% from 337%.
