Abstract
Cyclohexyl-phosphoramidic acid diphenyl ester (CPADE) was synthesized and characterized by elemental analysis (EA), mass spectrum (MS), infrared spectroscopy (IR) and nuclear magnetic resonance (NMR). The thermostability of CPADE was measured by thermogravimetric analysis (TGA) and the melting temperature and the fusion enthalpy of CPADE were evaluated by using differential scanning calorimeter (DSC). The solubilities of CPADE in selected solvents were obtained by a gravimetric method. The experimental data were well correlated by the Wilson, nonrandom two liquid (NRTL), and universal quasichemical (UNIQUAC) equations. And the dissolution enthalpy, entropy, and the molar Gibbs energy of CPADE in the selected solvents are also calculated by the van't Hoff equation.
