THE VAPOR HEAL CAPACITIES OF ACETONE-CHLOROFORM, BENZENE-CARBON TETRACHLORIDE AND BENZENE-ETHANOL BINARY-MIXTURES

The vapor heat capacities of acetone-chloroform, benzene-carbon tetrac hloride and benzene-ethanol binary mixtures as a function of temperatu re and composition have been measured under atmospheric pressure in a multicomponent vapor flow calorimeter. It was found that the heat capa cities of benzene-carbon tetrachloride vapors display ideal behavior, while those of acetone-chloroform vapors demonstrate positive deviatio n and those of benzene-ethanol vapors, negative deviation from the ide al linear additive values. These phenomena are explained and discussed .
