Title

Calorimetric Study of the Xylose + Ethanol + Water System at High Ethanol Concentrations at 45°C

Abstract

Enthalpies of mixing of 50% (w/w) xylose + water solutions with ethanol and aqueous ethanol solutions have been measured at 45°C. These results have been combined with the enthalpy of dilution in water, partial molar excess enthalpies of water, and the enthalpy of solution of anhydrous xylose in water to obtain the differential enthalpy of solution of xylose in ethanol solutions containing up to 4.5% (w/w) xylose and 15% water. The standard enthalpy of solution in ethanol is considerably more endothermic than in water and is decreased by increasing concentrations of either water or xylose. © 1987 American Chemical Society.
