Measurement and correlation of solubility of diphenyl carbonate in alkanols / Dongwei Wei ; Yanhong Pei in Industrial & engineering chemistry research, Vol. 47 n°22 (Novembre 2008)

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.
