Organic reactions in melts and solids. Part IX. Thermogravimetric studies of reactions between acetanilide and aromatic monocarboxylic acids

Abstract

Isothermal thermogravimetric analysis was used to follow the transacylation reactions in melts of acetanilide with 3,5-dinitrobenzoic acid, 1-naphthoic acid, and 4-methoxybenzoic acid. Reactions were carried out at 106 and 110° with anhydrous aluminium chloride as catalyst. They were found to be of the second order (first order in acetanilide and in the acid). The correlations of rate coefficients with acid strengths and with the concentrations of reactants and catalyst were studied.
