ABSTRACT
Liquid-liquid equilibria for the systems water + benzonitrile + N-methylacetamide and water + benzonitrile + N,N-dimethylacetamide were measured in the temperature range of (288.15 to 328.15) K at atmospheric pressure. Phase diagrams, including binodal curves and tie lines, are reported for both systems at each temperature. The plait point compositions have been calculated by Hand s method. Enthalpy changes for the transfer of the substituted acetamide from benzonitrile to water are given.
