ABSTRACT
Using the steady-state method, the solubilities of terephthalic acid(1) in binary acetic acid(2) +water(3) solvent mixtures in a specially contrived vessel have been measured as a function of temperature in the temperature range 423.15 513.15K and solvent composition range from x2 = 1.000 to 0.3103 (molar fraction). The experimental solubilities are correlated with the Apelblat equation. The calculated results show good agreement with the experimental solubilities.
