Document Type and Number:

WIPO Patent Application WO/2002/070474

Kind Code:

A1

Abstract:

A process for continuously producing a lactam in water at a high temperature under a high pressure. Namely, a process for producing a lactam characterized by selectively synthesizing the lactam without causing hydrolysis by introducing an oxime into flowing water at a high temperature under a high pressure, wherein the lactam is continuously synthesized at a high rate from the oxime in water at a high temperature of 250 °C or more under a high pressure of 12 Mpa or more.
