Abstract: 2-NITROCYCLOHEXANONE IS CLEAVED IN THE PRESENCE OF 6AMINOCAPROIC ACID AS A CATALYST. 6-NITROCAPROIC ACID IS PRODUCED WHICH CAN BE REDUCED WITH HYDROGEN TO 6AMINOCAPROIC ACID AND THE LATTER CYCLIZED TO CAPROLACTAM BY HEATING IN FAIRLY DILUTE AQUEOUS SOLUTION, LESS THAN 25%. THE CAPROLACTAM FORMATION IS AN EQUILIBRIUM REACTION AND SOME AMINOCAPROIC ACID REMAINS WHICH CAN BE SEPARATED AND USED AS A CATALYST IN THE CLEAVAGE OF THE 2-NITROCYCLOHEXANONE.
