LACTAM SYNTHESIZING METHOD

摘要

A method of continuously manufacturing lactam under high temperature and high pressure fluid, characterized by comprising the step of leading ketone and a hydroxylamine compound in a reaction field under high temperature and high pressure conditions of circulating fluid to efficiently synthesize lactam in a short time, whereby lactam can be rapidly synthesized continuously from ketone under the high temperature and high pressure fluid conditions of 175<°>C or higher in temperature range and 7 MPa or higher in pressure range.
