| titleOfInvention | Process for the preparation of E-caprolactam |
| abstract | Process to prepare ε-caprolactam startingnfrom a starting mixture containing a 6-aminocaproatenester, in which in a first step (1) the 6-aminocaproatenester is converted into 6-aminocaproic acid and 6-aminocaproamidenby reaction with water in the presencenof ammonia at a temperature of between 50 and 250°C,nfollowed by a separate or simultaneous removal ofnalcohol(s), and in a subsequent step (2) the 6-aminocaproicnacid and 6-aminocaproamide are cyclizisednat an elevated temperature, wherein in step (1) the 6-aminocaproatenester is converted into 6-aminocaproicnacid and 6-aminocaproamide in the presence of an amountnhigher than 2 wt.% and less than or equal to 25 wt.% NH 3 n(relative to the total amount of organic compounds,nwater and ammonia present in step (1)). |
