Determination of the solubility, dissolution enthalpy and entropy of 3-pentadecylphenyl acrylate in different organic solvents
The solubility of 3-pentadecylphenyl acrylate in n-butanol, toluene, acetone, dichloromethane, n-heptane and ethyl acetate were measured at the temperatures ranging from 273.15 to 297.15 K at atmospheric pressure using a laser detecting system. The solubility data were correlated by the modified Buchowski-Ksiazczak lambda h equation and Apelblat equation. The calculated results show that the correlation of the modified Apelblat equation has less deviation than that of the lambda h equation. The dissolution enthalpy and entropy of 3-pentadecylphenyl acrylate were predicted with the solubility data using van't Hoff equation. (c) 2012 Elsevier B.V. All rights reserved.
