The reaction of secondary amine and urea gave N, N-disubstituent with the evolution of ammonia, but N, N, N, N-tetrasubstituent could not be obtained. This is clear from its reaction mechanism and it is not concerned with the reaction velocity. The following three kinds of secondary amines may be considered when R=alkyl group and R=aryl group: As examples of these, di-n-butylamine, ethylaniline, and diphenylamine were chosen and their reaction with urea have been investigated. The reaction velocities of these secondary amines and urea were in order of An introduction of aryl group caused a rapid decrease in reaction velocity. For this reason, the secondary amines, other than aliphatic secondary amine, gave the formation of cyanuric acid and N, N-disubstituted urea could not be obtained.
