Activity coefficients and excess Gibbs energy of binary mixtures of N, N-dimethyl formamide with selected compounds at 95.5 kPa

Abstract

Bubble point temperatures at 95.5 kPa, over the entire composition range, are measured for the binary mixtures of N, N-dimethyl formamide with: acetophenone, aniline, bromobenzene, chlorobenzene and N, N-dimethyl acetamide, employing a Swietoslawski-type ebulliometer. Liquid phase mole fraction versus bubble point temperature measurements are well represented by the Wilson model. Computed values of the activity coefficients and excess Gibbs energy are presented and discussed.
