Novel separation of raw materials of bio-based plastics using ionic liquids

研究了离子液体浸渍的多孔固体结构离子液膜在生物降解聚乳酸原料乳酸和生物燃料丁醇回收中的应用。在乳酸盐分离中，我们开发了以Aiquat 336为离子液体，以盐酸溶液为回收溶液的聚合物包结膜，以减少海水淡化过程。在丁醇分离中，我们开发了用于渗透汽化的支撑式离子液膜。

A ionic liquid membrane, which is a porous solid structure impregnated with an ionic liquid, was studied for applying the separation and recovery of lactic acid, which is the raw material of biodegradable polylactic acid, butanol recovery, which is one of the biofuel. In lactate separation, we developed polymer inclusion membrane using Aliquat 336 as an ionic liquid and hydrochloric acid solution as the recovery solution to reduce a desalination process. In butanol separation, we developed the supported ionic liquid membrane for pervaporation.
