Abstract
Water forming in benzanilide synthesis from benzoic acid and aniline catalyzed by titanium tetrabutoxide does not influence the activity of the catalyst. The role of mass transfer processes associated with water removal from the system is revealed. The reversible deactivation of titanium tetrabutoxide by water occurs in the absence of vigorous water boiling and distillation. The stability of titanium tetrabutoxide to water is explained by the formation of titanium benzoate complexes at the initial stage of the reaction. These complexes enhance the resistance of the catalyst structure to hydrolysis.
