PROCESS FOR PRODUCING CYCLIC LACTAMES

摘要

Production of cyclic lactames by reaction with water of aminocarboxylic acid compounds of general formula (I) in which R1 is -OH, -O-C1-C2-alkyl or -NR2-R3, R2 and R3 are mutually independently hydrogen, C1-C12 alkyl and C5-C8 cycloalkyl and m is a whole number from 3 to 12. The reaction is conducted in the liquid phase using heterogeneous catalysts.
