摘要：

In an equilibrium vessel, the solubility of diphenyl carbonate (DPC) in alkanols was measured in the temperature range of 283-338 K, using a method in which an excess amount of solute was equilibrated with the alkanol solution. The liquid concentrations of the investigated DPC in the saturated solution were analyzed by spectrophotometry. The solubility data have been correlated as functions of the temperature. Activity coefficients for DPC have been calculated by means of the Wilson, NRTL, and UNIQUAC equations and, with them, were correlated solubility data that were compared with the experimental data. The best correlation of the solubility data has been obtained by the Wilson equation, by which the average root-mean-square deviation of temperature for the seven systems is 1.72 K.
