Measurement and Correlation of Solubility of Diphenyl Carbonate in Alkanols

Abstract

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.

Determination and Correlation of Solubility of N-tert-Butylacrylamide in Seven Different Solvents at Temperatures between (279.15 and 353.15) K

“…The values of Δ fus H m and T m can be determined by the differential scanning calorimetry (DSC). 17 Figure 3 shows the heating DSC curves of TBA at the heating rate of 10 K/min. From Figure 3, the enthalpy of fusion and the melting temperature are determined to be 21.57 kJ·mol −1 and 401.65 K for TBA.…”

“…In addition, α12 is a constant that reflects the non-randomness of the mixture and its value generally varies between 0.20 and 0.47 (Wei and Pei, 2008). Different values of α12 were chosen to correlate the solubility data of 1-AH.…”

“…Considering the solid-liquid equilibrium for the system solid TCH(1)/pure solvent(2), the solubility (x 1 ) of TCH at different temperatures can be expressed by [8].…”

“…Generally, the second term of equation (2) can be neglected due to its very small value. Thus, the equation (2) can be transformed as [8]:…”
