摘要
对丙交酯提纯技术,包括萃取,精馏,熔融,结晶技术作了介绍,分析了不同工艺的优缺点,并从工程设计的角度进行总结,指出熔融结晶技术能耗低,操作灵活,绿色环保,是一个相对比较适合的分离提纯技术。
The lactide purification process such as extraction, distillation, melt crystallization are introduced. The advantages and disadvantages of different process are analysed. The conclusion is made on the opinion of engineering design. It is pointed out that the melt crystallization process have the advantages such as low energy consumption, flexible operation, green environmental. It is a relative suitable separation and purification process.
