PRODUCTION OF EPSILON-CAPROLACTAM

摘要

PURPOSE:To efficiently produce epsilon-caprolactam by sufficiently recovering the lowered activity of a catalyst and further improving the life time of the catalyst. CONSTITUTION:A method for producing epsilon-caprolactam characterized by the use of a solid catalyst regenerated by bringing ammonia into contact with a catalyst with a lowered activity, in production of epsilon-caprolactam from cyclohexanone oxime in the presence of the solid catalyst in a gaseous phase reactional condition.
