ABSTRACT
The solubilities of m-phthalic acid in acetone, ethanol and acetic ether were experimentally determined in the temperature range from 278 K up to near the normal boiling points at about 5 K intervals by a gravimetric method. The measured solubility data were correlated with the ?h equation (Buchowski Ksiazczak equation) and the calculated results show good agreements with measured data. The excess molar mixing enthalpies at the saturation points were calculated based on the regressed model parameter and the interactions between m-phthalic acid and the solvents were qualitatively discussed.
