摘要
介绍了聚乙烯醇生产过程中醇解废液的回收工艺,综述了催化水解精馏技术、萃取精馏技术和加盐萃取精馏技术在醇解废液回收中的应用研究进展,指出加盐萃取精馏技术将是未来的发展方向.
In the production of polyvinyl alcohol, great deal of vise liquid will appear as by product, the recycling process of vise liquid was introduced, progress of catalytic hydrolysis distillation, extractive distillation, salt effect extractive distillation were reviewed. Salt effect extractive distillation was the trend of further study.
