摘要: 渗透汽化作为一种新型的膜分离技术应用于乙酸的分离,可以优先透水或乙酸。特别是应用在发酵法制备乙酸等低酸含量溶液的分离中,可以优先透酸制备高纯度的乙酸,具有显著的优势。本文综述了渗透汽化技术在分离纯化乙酸中所涉及的膜材料、耦合工艺及其应用现状,并展望了其发展趋势。

Abstract: Pervaporation is used in acetic acid separation as a new type of membrane separation technology. Preferential permeation of either water or acetic acid is applied to the pervaporation separation of biofermented acetic acid or other low concentration acid solution. Acetic acid can be highly purified by the separation technology. The pervaporation technology in the separation and purification of acetic acid is discussed,including the membrane materials,coupling technology and its application. The development trend of pervaporation is prospected.
