摘要：
Densities and heat capacities of methanol + acetonitrile mixtures were determined over the whole composition range at 5 and 25-degrees-C. Apparent and partial molar volumes and heat capacities for both components of the mixture were calculated from these data. These functions for acetonitrile run monotonously over the whole composition range of the mixture at both temperatures, while those for methanol exhibit extrema (volumes - minimum and heat capacities - maximum) at high acetonitrile content. The reasons of the observed behavior of the system are discussed.
