The octane-enhancers such as Dimethyl carbonate (DMC), t-Amyl methyl ether (TAME) and Methyl-t-butyl ether (MTBE) have attracted much attention in recent years as a potential gasoline additive. These octane-enhancers are produced by essentially the reaction with methanol (MeOH) over an acidic catalyst. As the reaction is reversible, it is required to separate unreacted MeOH from the product solution for recycling to the reactor. However, MeOH forms an azeotrope with these octane-enhancers, which is difficult to separate by distilllation.As one promising separation technology from view of energy-saving point, pervaporation using hydrophilic membranes have been applied to preferentially permeate MeOH from MeOH-organic mixtures.In pervaporation of water-alcohol mixtures, the hydrolyzed polyacrylonitrile and polyion complex membranes, which are hydrophilic membranes were found to provide with high flux and emhanced separation factor. These membranes was also effective for the separation of MeOH from the azeotropic MeOH-DMC or TAME mixture. From the father investigation, the organic-inorganic hybrid membrane was useful to the separation of MeOH-MTBE mixture.Moreover, the energy efficiency was evaluated by using simulator and the process with membrane separation was found to be available for the production of MTBE.

碳酸二甲酯（DMC）、甲基叔戊基醚（驯服）、甲基叔丁基醚（MTBE）等辛烷值提高剂作为一种潜在的汽油添加剂，近年来受到广泛关注。这些辛烷值增强剂基本上是通过与甲醇（MeOH）在酸性催化剂上的反应产生的。由于反应是可逆的，因此需要从产物溶液中分离未反应的MeOH以再循环至反应器。从节能角度考虑，亲水性膜渗透汽化技术已被应用于从甲醇-有机物混合物中优先渗透甲醇的分离，在水-醇混合物的渗透汽化分离中，水解聚丙烯腈和聚离子复合膜发现其为亲水性膜，提供高通量和增强的分离因子。这些膜对于从共沸MeOH-DMC或驯服混合物中分离MeOH也是有效的。研究表明，有机-无机杂化膜可用于甲醇-甲基叔丁基醚混合物的分离，并通过模拟装置评价了膜分离过程的能量效率，证明了膜分离过程可用于甲基叔丁基醚的生产。
