Abstract
It is an object of the present invention to provide a method of continuously producing a lactam in high-temperature high-pressure water, and the present invention relates to a method for producing a lactam characterized by selectively synthesizing the lactam without bringing about hydrolysis by introducing an oxime into flowing high-temperature high-pressure water, wherein the lactam is continuously synthesized at a high rate from the oxime in water at a high temperature of at least 250° C. and a high pressure of at least 12 MPa.
