Heats of mixing. II. Acetonitrile and nitromethane systems

Abstract

The heats of mixing at 45.00 �C have been measured at intervals over the whole composition range for the systems : acetonitrile+carbon tetrachloride, acetonitrile+benzene, acetonitrile +nitromethane, nitromethane + carbon tetrachloride, and nitromethane+benzene. These data, together with the excess free energy data of Brown and Smith (1954, 1955a, 1955b), have been used to calculate the excess entropy of mixing for these systems.
