摘要:
Method for enantioseparation of a chiral system with compound formation comprising a pair of enantiomers. The method comprises the steps of: placing the chiral system to be processed, which is optically enriched by a target enantiomer, in the 3-phase region of the ternary phase diagram of chiral compound forming systems to achieve the establishment of the solid/liquid phase equilibria; phase-separating the liquid and solid phase formed by the placing step; shifting the eutectic composition of the remaining liquid towards a lower eutectic composition (xE) until the overall composition is located in the 2-phase region of the ternary phase diagram of chiral compound forming systems; and performing crystallization in the 2-phase region of the ternary phase diagram for obtaining the target enantiomer in the solid phase. In some cases the shifting step can be skipped.
摘要(中):
用于与化合物的形成包括一对对映异构体的手性体系的对映体拆分方法。 该方法包括以下步骤:将要处理的手性系统,所有这一切都被光学地由目标对映异构体富集的,在形成系统的手性化合物的三元相图的3相区,以实现建立固/液相的 平衡; 相分离由放置步骤形成的液相和固相; 移向低共熔组合物(XE)的剩余液体的共晶组成,直到总组成位于手性化合物形成体系的三元相图的2相区; 并在三元相图的2相区进行结晶为在固相中获得目标对映体。 在一些情况下,移位步骤可以跳过。
