抄録

The rate constants of the thermal dissociation of 1,3-dibenzylurea and 1-isopropyl-3,3-diethylurea in alcohols were determined. The rates of dissociation in fatty acids are faster than those in alcohols and it can be said that the process of protonation of ureas by solvents plays an important role in the dissociation. In the case of dissociation in alcohols, the reaction seems to proceed by a base catalysis. And the intermediate complex containing two alcohol and one urea molecules was considered. The experimental results were reasonably explained by the proposed mechanism.
