ABSTRACT
In this paper, the solubilities of maleic acid in different compositions of acetone-ethyl acetate mixtures were measured at the temperature range from 285.15K to 324.25K under atmospheric pressure by the gravimetric method. These data were correlated with Apelblat equation and Buchowski-Ksiazczak eh equation. Both equations provided an accurate mathematical representation of the experimental results. The root-mean-square deviations (rmsd) of the Apelblat equation were lower than those of eh equation, which indicated that the Apelblat equation could regress the solubility data much better than the eh equation for this system. This study provided valuable data not only for optimizing the process of purification of maleic acid in industry but also for further theoretical studies.
