Acetic acid is an essential intermediate chemical and belongs to the top 50 commodities of the chemical industry. Dehydration of acetic acid/water mixture is an indispensable process for the final acetic acid product. As an effective alternative technique for energy-intensive distillation, pervaporation is getting significant attention for this target separation due to its high efficiency, low energy requirements, and eco-friendly nature. In the present review, the advances in pervaporation membranes, especially polymeric membranes, composite membranes, zeolite membranes, and sol–gel derived ceramic membranes are covered for dehydration of acetic acid/water mixture. The developed strategies to overcome the tradeoff between membrane hydrophilicity and acid resistance are discussed for each kind of membrane with a particular focus on tuning framework Si/Al ratio and Al atom spatial distribution of zeolite membranes, and development of hybrid silica membranes. Thus, pervaporation membranes performance is described along with future prospects and challenges for their commercialization as acid-resistant membranes. In addition to this, we have critically discussed the use of hollow fiber technology for the dehydration of acetic acid and stressed the need of acid-resistant membranes for esterification reactions to improve the yield of the final product.

乙酸是必不可少的中间化学品，属于化学工业的前50名商品。乙酸/水混合物的脱水是最终乙酸产物必不可少的过程。作为高耗能蒸馏的一种有效的替代技术，全蒸发由于其高效，低能耗和生态友好的特性而受到了广泛关注。在本综述中，渗透蒸发膜，特别是聚合物膜，复合膜，沸石膜和溶胶-凝胶衍生的陶瓷膜的进展涵盖了乙酸/水混合物的脱水。针对每种膜，讨论了克服膜亲水性和耐酸性之间折衷关系的已开发策略，特别侧重于调整沸石膜的硅/铝比和铝原子空间分布框架，以及混合二氧化硅膜的开发。因此，描述了全蒸发膜的性能以及将其作为耐酸膜商业化的未来前景和挑战。除此之外，我们已经严格地讨论了中空纤维技术在乙酸脱水中的应用，并强调了耐酸膜用于酯化反应以提高最终产物收率的需要。介绍了渗透膜的性能以及将其作为耐酸膜商业化的未来前景和挑战。除此之外，我们已经严格地讨论了中空纤维技术在乙酸脱水中的应用，并强调了耐酸膜用于酯化反应以提高最终产物收率的需要。描述了全蒸发膜的性能以及将其作为耐酸膜商业化的未来前景和挑战。除此之外，我们已经严格地讨论了中空纤维技术在乙酸脱水中的应用，并强调了耐酸膜用于酯化反应以提高最终产物收率的需要。
