Preferential solvation in mixed solvents. 15. Mixtures of acetonitrile with organic solvents

The preferential solvation parameters for the mutual association of acetonitrile with a co-solvent in their binary mixtures and for the self-association of acetonitrile in these mixtures, and the self-association of each of these components at infinite dilution in the other component as solvent have been determined. The co-solvents studied include dichloromethane, acetone and nitromethane that form practically ideal mixtures with acetonitrile and 1,2-dichloroethane and chloroform that nearly do so, as well as benzene, toluene, chlorobenzene, tetrarchloromethane, methanol, ethanol, acetic acid, formamide, dimethylformamide, and dimethylacetamide, which show appreciable preferential solvation.
