ABSTRACT

Densities of binary liquid mixtures of N-ethylformamide (NEF) with tetrahydrofuran (THF), 2-butanone (B) and ethylacetate (EA) were measured at temperatures from (293.15 to 313.15) K and at atmospheric pressure over the whole composition range. Excess molar volumes, VE, have been obtained from the experimental densities and were fitted to Redlich-Kister polynomial equation. The VE values for all three mixtures are negative over the entire composition and temperature ranges. VE values become more negative as the temperature increases for all studied binary mixtures. Other volumetric properties, such as thermal expansion coefficients, partial molar volumes, apparent molar volumes and partial molar excess volumes have been calculated, too.
