Calorimetric study of molecular interactions in mixtures of substances containing carbonyl groups

A Tian-Calvet type calorimeter has been used to determine molar excess enthalpies, H E, as a function of concentration at atmospheric pressure and 298.15 K for some binary liquid mixtures containing linear ketones with tetrachloromethane or benzene and linear diketones with n-heptane or cyclohexane....

Description
Summary:A Tian-Calvet type calorimeter has been used to determine molar excess enthalpies, H E, as a function of concentration at atmospheric pressure and 298.15 K for some binary liquid mixtures containing linear ketones with tetrachloromethane or benzene and linear diketones with n-heptane or cyclohexane. The experimental H E results are interpreted in terms of molecular interactions and of the “homoproximity effect”.
