摘要/Abstract

摘要：

采用激光法测定了碳酸二苯酯(DPC)在乙醇碳酸二乙酯(DEC)混合溶剂中的溶解度。结果表明，在283.15～333.15 K下，碳酸二苯酯在混合溶剂中的溶解度随温度的升高而增大;相同温度下，溶解度随着乙醇浓度的增大而减小。进一步选用Wilson方程和λh方程拟合DPC的溶解度，根据实验数据回归了模型参数，溶解度拟合值与实验值非常吻合，平均误差小于2.0%。计算表明Wilson方程对碳酸二苯酯-乙醇-碳酸二乙酯体系的计算精度更高些。

Abstract:

The solubility of diphenyl carbonate (DPC) in ethanoldiethyl carbonate (DEC) was determined with the laserscattering methodThe results showed that the solubility of DPC in the mixed solvents always increased with rising temperature.At 283.15—333.15 K, the solubility decreased with the increase of ethanol concentrationThe experimental data were further correlated with Wilson equation and λh equation, and model parameters were regressed For the DPC- C₂H₅OH-DEC system, the agreement between the experimental solubilities and calculated values was satisfactoryThe mean deviation was less than 2.0%.Obviously, the correlated results using Wilson equations were superior to those obtained from λh equation.
