Disclosed is a method for resolving an optical isomer from a racemate by means of electrodialysis. Specifically, an electrodialysis technique is used in an enzymatic resolution process, mainly in the separation of products after enzymatic resolution. Taking a preparation process for D-pantolactone as an example, the key point is that D-pantoic acid and L-pantolactone are separated from an enzymatic resolution solution by means of an electrodialysis method, which replaces the existing organic solvent extraction method. The process method is simple and easy to operate, has a high yield of D-pantoic acid of a good purity, greatly reduces the usage amount of an organic solvent, reduces production costs and is environmentally friendly, such that the working environment of workers can be improved to a great extent, and the operation safety index is improved.
本发明公开了一种通过电渗析从外消旋体中分离光学异构体的方法。具体来说,电渗析技术用于酶解过程,主要是酶解后产物的分离。以 D-泛酰内酯的制备工艺为例,其要点是通过电渗析方法从酶解溶液中分离出 D-泛酸和 L-泛酰内酯,从而取代现有的有机溶剂萃取法。该工艺方法简单易操作,D-泛酸收率高,纯度好,大大减少了有机溶剂的用量,降低了生产成本,而且环保,可极大地改善工人的工作环境,提高操作安全指数。
