Title:
PROCESS FOR PRODUCING LACTAM
Document Type and Number:
WIPO Patent Application WO/2002/076942
Kind Code:
A1
Abstract:
A process for efficiently and continuously producing a lactam in high-temperature high-pressure water, characterized by comprising: introducing an oxime as a substrate and an acid into a reaction zone through which high-temperature high-pressure water is flowing or introducing an oxime into high-temperature high-pressure water which contains an acid and is flowing; and thereby elevating the temperature of the substrate in a short time under the given high-temperature high-pressure conditions and reacting it to efficiently synthesize a lactam while inhibiting hydrolysis of the oxime. In the process, a lactam can be efficiently and continuously synthesized at a high rate from an oxime with the aid of an acid catalyst in high-temperature high-pressure water having a temperature of 250 °C or higher and a pressure of 15 MPa or higher.
