The measurement of activity coefficients for solutes at infinite dilution with mixed solvents formamide + glucose, or + fructose, or + sucrose using a gas liquid chromatography at 298.15 K

Using gas liquid chromatography, activity coefficients for nine solutes at infinite dilution (γi∞) in stationary solvent of formamide + glucose, + fructose and + sucrose at 298.15 K have been measured. Linear dependence of ln γi∞ on the mole fraction of sugar was observed.
