Measurement and Correlation of the Solubility of Terephthalic Acid in Six Pure Solvents and Five Binary Mixtures

The goal of this work was to measure the solubility of terephthalic acid (TA) in six pure solvents (2-ethyl-1-hexanol (2EH), dimethyl sulfoxide, 1-methyl-2-pyrrolidinone, N,N-dimethylformamide, N,N-dimethylacetamide, and pyridine) and five binary mixtures (composed of 2EH and 5 or 10% w/w another solvent) from 313.15 to 363.15 K at atmospheric pressure 101.3 kPa. Experiments were performed by an isothermal method employing an in situ filter to...
