The vapour pressure of water as a function of solute concentration above aqueous solutions of fructose, sucrose, raffinose, erythritol, xylitol, and sorbitol

The vapour pressure of water above an aqueous solution of sucrose at <f>T=298.06</f> K has been measured for 9 sucrose mole fractions up to 0.12. Vapour pressure measurements have also been made on aqueous solutions of meso-erythritol, xylitol, sorbitol, fructose, and raffinose at <f>T=317.99</f> K. The excess molar enthalpy has also been determined for the aqueous sucrose system at <f>T=318.15</f> K. The data obtained are compared to literature data for related systems and the effects of the solutes on solution structure are discussed. [Copyright &y& Elsevier]
