Using dynamic method and the laster monitoring observation technique, the solubility of D-xylose in water + acetic acid, and water + propionic acid were measured over the temperature range from (296.65 to 325.45) K at atmospheric pressure. The solubility data of D-xylose in the mixtures of water + acetic acid, and water + propionic acid was found to increase with increasing temperature and decrease with increasing volume fractions of acetic acid, and propionic acid in aqueous solution. The experimental data were correlated by using the Apelblat equation, the lambda-h equation and the ideal equation. The results showed that these three models agreed well with the experimental data, and the Apelblat equation was found to regress the solubility data better than the other two models. The standard enthalpy, standard entropy, and Gibb free energy change of solution of D-xylose were calculated from the solubility data by using the Apelblat model.
