摘要：The solubilities of pentachloropyridine (PCP) and tetrachloropyridine (TECP) in methanol, ethanol, and 2-propanol were measured respectively using an analytical method from (293.15 to 355-15) K. From the thermodynamics theory of solid-liquid equilibrium, the solubility model was derived, and the experimental data were regressed. The average deviation of the model was smaller than 5%. The fusion enthalpies (Delta H-fus) of PCP, TECP, and their infinite-dilution activity coefficientes (gamma(infinity)(2)) in methanol, ethanol, and 2-propanol were obtained by regressing the experimental data.
