On the Thermal Dissociation of Organic Compounds. XV. Thermal Dissociation of Urethans in the Presence of Aromatic Amines

Abstract
N-Phenyl phenylurethans dissociate readily into their component compounds in the presence of aliphatic amines and the plot for the second order reaction shows a straight line throughout a large portion of the dissociation. However, the rate of the dissociation of urethans in aromatic amines is much slower than in aliphatic ones and shows a tendency of increasing rate as the dissociation proceeds. The anomalous acceleration of the dissociation is due to the reaction products, urea and phenol.
