| titleOfInvention | Process for the preparation of ¹-caprolactam |
| abstract | Process for the preparation of .epsilon.-caprolactam starting from 5-formylvalerate acid, ester or amide (aldehyde compound) in which a reaction in the presence of ammonia and hydrogen and a subsequent cyclization of the reaction products thus formed (.epsilon.-caprolactam-precursors) to .epsilon.-caprolactam is performed in the presence of water, wherein that the following steps are performed (a) contacting the 5-formylvalerate acid, ester or amide with ammonia and water under non-hydrogenation conditions, (b) contacting the resulting mixture of step (a) with hydrogen in the presence of ammonia under hydrogenation conditions, in which the water content is higher than 10 wt.%, (c) heating the resulting mixture of step (b) at a temperature between 200 and 350°C in order to convert the reaction products of step (b) to .epsilon.-caprolactam. |
