PROCESSES FOR PRODUCING CAPROLACTAM AND DERIVATIVES THEREOF FROM FERMENTATION BROTHS CONTAINING DIAMMONIUM ADIPATE, MONOAMMONIUM ADIPATE AND/OR ADIPIC ACID

摘要

Processes for making caprolactam (CL) from monoammonium adipate (MAA) and/or adipic aicd (AA) obtained from a clarified diammonium adipate-containing (DAA- containing) fermentation broth or MAA-containing fermentation broth and converting the MAA or AA to the CL with hydrogen in the presence of a catalyst at selected temperatures and pressures.
