USE OF SHAPED BODIES AS A CATALYST FOR THE PRODUCTION OF CAPROLACTAM |
摘要 |
The invention relates to the use of essentially shaped bodies containing a catalytically active oxide as a catalyst comprising no soluble constituent, under the reaction conditions, for the production of cyclic lactams by reacting aminocarboxylic acid nitriles with water in aqueous phase, in a fixed bed reactor. This catalyst is composed of shaped bodies which can be obtained by shaping the oxide into shaped bodies and by treating the oxide with an acid which is hardly soluble, having 0.1 to 30 % by weight of the oxide, before or after the shaping process. |
