Abstract: A PROCESS FOR THE PREPARATION OF E-CAPROLACTAM BY CONTACTING CONTINUOUSLY WITH STEAM E-AMINOCAPROIC ACID, E-CAPROAMIDE OR A MIXTURE OF THE TWO AT A TEMPERATURE OF 150-400*C., WHILE DISCHARGING THE STEAM FROM THE REACTION SYSTEM. IN THIS PROCESS A SUBSTANCE NON-VOLATILE AND ACIDIC UNDER REACTION CONDITIONS CAN BE PREFERABLY USED AS CATALYST. BY THIS PROCESS, E-CAPROLACTAM CAN BE PRODUCED WITH HIGH YIELD WITHOUT FORMATION OF AMMONIUM SULFATE.

Abstract: The invention relates to a method for preparing 6-aminocaproic acid (hereinafter also referred to as ‘6-ACA’) using a biocatalyst. The invention further relates to a method for preparing ε-caprolactam (hereafter referred to as ‘caprolactam’) by cyclising such 6-ACA. The invention further relates to a host cell, a micro-organism, or a polynucleotide which may be used in the preparation of 6-ACA or caprolactam.
