Abstract

Abstract: The activity coefficients of acetone, ethanol, and acetonitrile in aqueous solutions of sucrose or glucose were measured by headspace gas chromatograpy at 298.1K.The variations of activity coefficients of three nonaqueous solutes (lnr)with concentration of sugar are explained preliminary in term of the hydration of equatorial OHof sugar molecules, the mixing order of solvents, and the interaction of molecule between solute and sugar.

Key words: Headspace gas chromatography, Activity Coefficient, Equatorial hydroxy group, Mixing order of solvents, Intermolecular action
