Summary
The ternary mixture methanol (MeOH)/formamide (Form)/acetonitrile (MeCN) was studied by means of refractive index and density measurements. Data for a total of 22 ternary mole fractions, and 19 binary mole fractions for each formamide containing mixture, as well as values from the previously studied methanol/acetonitrile mixture were obtained and evaluated. Excess properties were computed and modeled by polynomial equations, namely Redlich-Kister for binary fractions and Cibulka for ternary mixtures. Partial molar volumes were likewise calculated and together with previously published values allowed the interpretation of structural effects associated with molecular interactions.
