Abstract

A method for resolving a dl mixture of a 3-fluorine-dl alanine compound, which consists of preparing a saturated solution of said dl mixture in a dissolution zone transforming said solution into a supersaturated solution of said dl mixture to contact said solution supersaturated with crystals of the l isomer, thereby crystallizing the l isomer of said solution, separating the mother liquor and contacting them with crystals of the d isomer, thereby crystallizing the 3-fluoro-d-alanine compound and recovering said compound from 3-fluorine d-alanine.
