Measurement of activity coefficients of solutes at infinite dilution in (dimethyl sulfoxide plus acetamide, or formamide, or urea) using gas liquid chromatography at the temperature 298.15 K
Using gas liquid chromatography, activity coefficients of 12 solutes at infinite dilution (gamma(1)(infinity)) in the stationary solvent dimethyl sulfoxide + additives (acetamide, or formamide, or urea) at the temperature 298.15 K have been measured. The effect of composition of the mixed solvents on gamma(1)(infinity) and on selectivity S(i/j) has been discussed.
