Tермодинамічні властивості розчинів 2-ціано-3-[5-(феніл)-2-фурил]-2-пропенаміда та 2-ціано-3-[5-(4-метилфеніл)-2-фурил]-2-пропенаміда в органічних розчинниках
The fusion temperature of 2-cyano-3-[5-(phenyl)-2-furyl]-2-propenamide and 2-cyano-3-[5-(4-methylphenyl)-2-furyl]-2-propenamide and their temperature dependence of dissolution in acetonitrile, benzene, dimethylketone, ethyl acetate and 2-propanol have been determined. According to the temperature dependence the differential enthalpies and entropies of the solution were calculated. Taking into account the entropies of fusion the entropies and enthalpies of mixing were calculated at 298 K.
