Heat Capacities of Binary Mixtures of Acetic Acid with Acetic Anhydride and Methenamine at Different Temperatures

Abstract

Heat capacities of binary mixtures of acetic acid with acetic anhydride and methenamine were measured by a cooling method with a simple calorimeter from (308.15 to 333.15) K at atmospheric pressure with different compositions. The excess molar heat capacities of the binary mixture of acetic acid with acetic anhydride were calculated from the experimental data and were fitted to the Redlich-Kister equation.
