摘要：

Using dynamic method and the laser monitoring observation technique, the solubility of alpha-D-glucose in {water + (acetic acid or propionic acid)} was measured over the temperature range (297.55 to 331.45) K at atmospheric pressure. Its corresponding (solid + liquid) equilibrium data will provide essential support for industrial design and further theoretical studies. The solubility of alpha-D-glucose 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 solution equation. The results showed that these three models agreed well with the experimental values, and the Apelblat equation was found to regress the solubility data better than the other two models.
