Abstract: Excess molar volumes Vm E for binary mixtures of acetonitrile + dichloromethane, acetonitrile + trichloromethane, and acetonitrile + tetracloromethane at 25°C have been used to calculate partial molar volumes V̄i, excess partial molar volumes V̄i E, and apparent molar volumes Vφi of each component as a function of composition. The Vm E values are negative over the entire composition range for the systems studied. The applicability of the Prigogine-Flory-Patterson theory was explored. The agreement between theoretical and experimental results is satisfactory for the systems with dichloromethane and tetrachloromethane. For the unsymmetrical behavior of the system with trichloromethane, however, the agreement is poor.
