The solubility of diphenyl carbonate (DPC) in ethanoldiethyl carbonate (DEC) was determined with the laserscattering methodThe 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 concentrationThe 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 satisfactoryThe mean deviation was less than 2.0%.Obviously
the correlated results using Wilson equations were superior to those obtained from λh equation.
