Abstract
The solubility of ethyl ester of 2-cyano-3-[5-(4-methylphenyl)-2-furan] acrylic acid in acetonitrile, benzene, 2-propanol and ethyl acetate at temperatures 299.0-333.0 C was determined. From the temperature dependence of the solubility of ethyl ester of 2-cyano-3-[5-(4-methylphenyl)-2-furan] acrylic acid enthalpy and entropy of dissolution in investigated solvents were calculated. According to differential thermal analysis the enthalpy and entropy of melting of ethyl ester of 2-cyano-3-[5-(4-methylphenyl)-2-furan] acrylic acid were identified and adjusted to 298K. The influence of solvents polarity on the solubility and magnitude of enthalpy and entropy of mixing at 298K was established.
