摘要：

Using a synthetic method designed and installed with laser monitor on line, the solubility values of benzoic acid in ethanol, benzene, acetic acid and ethyl acetate were determined over the temperature range of 291.69-356.27 K. The solubility of benzoic acid in all cases investigated was found to increase with temperature. The two-parameters empirical and lambda h equations were used successfully to correlate experimental data of benzoic acid solubilities in organic solvents. The mean absolute error sigma of 65 data points correlating by two-parameters empirical equation and lambda h equation was less than 1%. Finally, molar dissolution enthalpy Delta H-sol of benzoic acid in organic solvents was determined with the newly obtained empirical equation parameters.
