Abstract: Vapour-liquid equilibrium data are given for the binary system dimethylformamide|ethylene glycol at 30ºC, 40ºC, and 50ºC. The data have been measured by a di erential semimicromethod. The dependence of the excess Gibbs energy on composition was expressed by the 4th-order Redlich— Kister, two-constant Margules, and NRTL equations. The system has negative deviations from ideal behaviour.
