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

离子液体膜是一种浸渍了离子液体的多孔固体结构，用于分离和回收生物可降解聚乳酸的原料乳酸，回收生物燃料之一的丁醇。在乳酸分离中，我们开发了聚合物包合膜，以Aliquat 336作为离子液体，盐酸溶液作为回收溶液，以减少脱盐过程。在丁醇分离中，我们开发了用于渗透蒸发的负载型离子液体膜。

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.
