Abstract
The coefficients of the virial expansion of the excess enthalpies of ternary aqueous solutions containing D-glucose and an alcohol (ethanol,n-propanol,n-butanol andtert-butanol) were determined at 25 °C. The trend of the cross coefficients versus the self coefficients of the alcohols exhibits a maximum in accordance with the system containingtert-butanol. This behaviour is similar to that found for the interaction of the same alcohols with any other hydrophilic solute examined up to now. The results are interpreted in terms of a prevailing release of water from the structured cospheres of the alcohols.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
