摘要：
The solubility of fumaric acid in aqueous alcohol solutions was experimentally measured over the temperature range of (278.15–333.15) K by employing an analytical stirred-flask method. The experimental data showed that the solubility of fumaric acid in the binary mixtures increases with increases of both temperature and mass fraction of the organic solvents. The experimental data were well correlated with the modified Apelblat equation and the Buchowski–Ksiazaczak λh equation. In addition, the calculated solubilities showed good agreement with the experimental results. It was found that the modified Apelblat equation gave better correlation results than the Buchowski–Ksiazaczak λh equation. The experimental results should be useful for optimizing the process of purification of fumaric acid in industry.
