IMPROVED PRODUCTION METHOD FOR L-(-)- CARNITINE FROM WASTE OF OPPOSITE CONFIGURATION

摘要

A process for preparing L-(-)-carnitine is disclosed which comprises acylating D-(+)-carnitinenitrile or D-(+)-carnitinamide to their respective acylderivatives which via acid hydrolysis yield D-(+)-carnitine which is converted to the lactone of L-(-)-carnitine. The lactone in a basic environment yields L-(-)-carnitine inner salt.
