- Abstract
Kinetic regularities of 2-hydroxyimino-1,3-diketones cyclocondensation with amines and ketones in the presence of zeolite NaA or azeotropic distillation of water were studied. Kinetic equations for the rate of formation of N,N-dicyclohexyl-3,5-dimethyl-4-nitrosoaniline and the effective activation energy have been established. New data confirm the previously proposed mechanism of the process and point to the catalytic effect of zeolite.
