Shu, Zirui published the artcileMeasurement and Correlation of Solubilities of 4-Methylbenzoic Acid and Terephthalic Acid in Eight Organic Solvents, Safety of N-Methylformamide, the main research area is solubility methylbenzoic terephthalic acid organic polar solvent thermodn.
The solubility of 4-methylbenzoic acid and terephthalic acid in N-methylformamide, 1,3-dimethyl-2-imidazolidinone, N-methylformanilide, 2-ethyl-1-hexanol, THF, cyclohexanone, acetophenone, and ethylene glycol di-Et ether was measured using the laser dynamic method under 101.3 kPa at the temperature ranging from 293.65 to 344.35 K. The measured results showed that the solubility of 4-methylbenzoic acid and terephthalic acid increased with the increasing temperature The solubility of 4-methylbenzoic acid is greater than that of terephthalic acid in the same solvents. The modified Apelblat model and the modified nonrandom two-liquid (NRTL) activity coefficient model were utilized to correlate the solubility of 4-methylbenzoic acid and terephthalic acid in each solvent. The calculated solubility agreed satisfactorily with the measured results with 1.67/1.91% averaged relative deviation (ARD) for terephthalic acid and 0.62/0.69% for 4-methylbenzoic acid in the modified NRTL/Apelblat model, resp. The result of the Akaike Information Criterion (AIC) anal. showed that the modified Apelblat model was better at correlating the solubility of 4-methylbenzoic acid in 1,3-dimethyl-2-imidazolidinone, ethylene glycol di-Et ether, THF, acetophenone, N-methylformamide, acetophenone, and terephthalic acid in 1,3-dimethyl-2-imidazolidinone; the modified NRTL model performs better in correlating the solubility of 4-methylbenzoic acid in N-methylformanilide, N-methylformamide, 2-ethyl-1-hexanol, and terephthalic acid in 2-ethyl-1-hexanol, 2-ethyl-1-hexanol, and cyclohexanone N-methylformanilide.
