L-A-AMINOCAPROLACTAM IS OBTAINED BY A PROCESS COMPRISING THE STEPS OF: (A) FORMING A COMPLEX OF D,L-A-AMINOCAPROLACTAM WITH A METAL ION SELECTED O D,L-A-AMINOCAPROLACTAM OF NI++, CO++, CU++, FE++, FE+++ AND ZN++; (B) OPTICALLY RESOLVING SAID D,L-A-AMINOCAPROLACT M (C) RECOVERING AND DECOMPOSING L-A-AMINOCAPRROLACTAM METAL COMPLEX TO AFFORD L-A-AMINOCAPROLACTAM PLUS METAL ION; AND (D) RACEMIZING D-A-AMINOCAPROLACTAM METAL COMPLEX TO AFFORD D-A-AMINOCAPROLACTAM METAL COMPLEX. METAL COMPLEX WHEREBY SEPARATE PHASES RICH IN D AND L-A-AMINOCAPROLACTAM METAL COMPLEX, RESPECTIVELY ARE OBTAINED; |
