| titleOfInvention | Method for producing aliphatic optically active alcohol |
| abstract | (57) [Summary] [Structure] a) a diester of an aliphatic racemic alcohol and a dibasic acid, and b) a non-optically active non-racemic alcohol having 16 or more carbon atoms, using a heat resistant lipase as a raw material solvent. Without using, the optically active alcohol produced by the transesterification reaction under reduced pressure and at 81 ° C. or higher under a substantially water-free condition is separated by distillation under reduced pressure. [Effect] By using a thermostable lipase, a raw material having a high melting point can be used without a solvent, a high-temperature transesterification reaction becomes possible, and the reaction time can be shortened. Further, since a raw material having a high melting point and a high boiling point is used, the optically active alcohol is highly purified from the reaction product in a high yield, and is simple, utilizing the difference in the physical properties of each component in the transesterification reaction product. It can be separated by means. Furthermore, the transesterification reaction and the separation and purification of the optically active alcohol can be carried out simultaneously. |
