Abstract

The solubilities of meso-Erythritol in water were experimentally measured from 283.15 K to 363.15 K at atmospheric pressure by employing the synthetic method. The experimental data were correlated by using the modified Apelblat equation and λh equation, the accuracy of which could meet the need of their industrial use. The dissolution enthalpy, dissolution entropy and molar Gibbs energy of the dissolution of meso-Erythritol in water were then calculated. The cooling crystallization of meso-Erythritol had been studied by using FBRM-PVM on the basis of the measured crystallization thermodynamics data. The experimental data and the correlation equations in this work can be used as essential data and models in the industrial manufacture process optimization and crystallizer design of meso-Erythritol.
