ABSTRACT

The solubility of 3,5-dimethoxybenzoic acid, 4-cyanobenzoic acid, 4-acetoxybenzoic acid, 3,5-diaminobenzoic acid, and 2,4-dichlorobenzoic acid in ethanol was measured by both static method and dynamic method over the temperature range from (298.15 to 318.15) K under atmospheric pressure. The experimental data were correlated by the modified Apelblat model. The results show that the solubility of each acid increases with increasing temperature in ethanol, and the data have greater accuracy when using the static method than when using the dynamic method.
