Determination of the solubility, dissolution enthalpy and entropy of 3-pentadecylphenyl acrylate in methanol-ethanol solutions

The solubilities of 3-pentadecylphenyl acrylate in methanol-ethanol mixture solvents of different compositions were measured at temperatures ranging from 273.15. K to 297.15. K at atmospheric pressure using a laser detecting system. The solubility data were correlated by the modified Apelblat equation and Buchowski-Ksiazczak . λh equation. Both the Apelblat equation and the Buchowski-Ksiazczak . λh equation can fit the solubility data well. The dissolution enthalpy and entropy of 3-pentadecylphenyl acrylate were predicted with the solubility data using modified Apelblat equation. © 2012 Elsevier B.V.
