%X 乙酸是一种重要的化工原料，可以广泛地应用在医药、染料、农药、合成纤维等各个行业。我国是目前世界上最大的乙酸生产国，但在乙酸生产的过程中有副产物水生成，因此乙酸脱水是其生产过程中不可缺少的环节。相对于传统的精馏技术，膜渗透汽化脱水具有效率高、操作简单、能耗低等优势，在乙酸脱水中具有广阔的应用前景。本文总结了近年来用于乙酸脱水渗透汽化膜的研究进展，主要从膜材料及其分离性能方面对现有乙酸渗透汽化脱水膜进行了分析。最后，对乙酸脱水膜的发展前景做出了展望。<br />
Acetic acid is an important chemical raw material, which can be widely used in medicine, dyes, pesticides, synthetic fiber and other industries. At present, China is the largest producer of acetic acid in the world, but there is by-product water formation in the process of acetic acid production, so acetic acid dehydration is an indispensable link in its production pro-cess. Compared with the traditional distillation technology, membrane pervaporation dehydration has the advantages of high efficiency, simple operation and low energy consumption, so it has a broad application prospect in acetic acid dehydration. This paper summarizes the research pro-gress of acetic acid dehydration pervaporation membranes in recent years, and mainly analyzes the existing acetic acid pervaporation membranes from the aspects of membrane materials and sepa-ration performance. Finally, the development prospect of acetic acid dehydration membrane is prospected.
