| titleOfInvention | PROCESS FOR THE PREPARATION OF ε-CAPROLACTAM |
| abstract | The present invention provides the 6-aminocaproic acid and 6- by reaction of 6-aminocaproic acid esters with water in the presence of ammonia at a temperature of 50-250 ° C., with or without the alcohol being removed in the first step (1). Preparing ε-caprolactam from a starting mixture containing 6-aminocaproic acid esters, which are converted to aminocaproamides, and then in step (2) the 6-aminocaproic acid and 6-aminocaproamide are cyclized at high temperature. As for the method,n n n In step (1) the 6-aminocaproic acid ester is present in the presence of at least 2 wt.% And 25 wt.% Or less NH 3 (relative to the total amount of organic compounds, water and ammonia present in step (1)). -Is converted to aminocaproic acid and 6-aminocaproamide. |
