SOLUBILITY, CORRELATION AND THERMODYNAMIC ANALYSIS OF GLUTARIC ACID IN PURE AND BINARY SOLVENT SYSTEM

Abstract

The solubility of Glutaric acid in pure water, 1-propanol and binary solvent (water + 1-propanol) was investigated over the entire composition range between 0 to 1 weight fraction of 1-propanol at (293.15, 295.15, 298.15, 300.15, 303.15, 305.15, 308.15, and 313.15) K. The Apelblat and van’t Hoff model was used to correlate the obtained solubility data and these models provide better correlation in this study. The molecular solute-solvent interactions were studied from the calculation of activity coefficients. Molecular simulation (DFT) was carried out to correlate solubility in the present study. van’t Hoff equation was used to determine thermodynamic parameters ( , %ζH, and % ζTS) of solution.
