Determination and correlation of solubilities of 1,2-bis (2-oxo-5,5-dimethyl-1,3,2-dioxyphosphacyclohexyl-2-imino) ethane in selected solvents
چکیده انگلیسی

1,2-Bis (2-oxo-5,5-dimethyl-1,3,2-dioxyphosphacyclohexyl-2-imino) ethane (BPEA) was prepared, and characterized by elemental analysis (EA), mass spectra (MS), infrared spectroscopy (IR) and nuclear magnetic resonance (NMR). The melting point and the enthalpy of fusion of BPEA were performed on differential scanning calorimetry (DSC), and the thermal stability of BPEA was tested by thermogravimetric analysis (TGA). The solubility of BPEA in selected solvents was measured by a static analytical method. The experimental data were correlated with different thermodynamic models, such as the empirical equation and non-random two liquid (NRTL), Wilson, Scatchard–Hildebrand, and universal quasi chemical (UNIQUAC) equations. The calculated results showed good agreement with the experimental data in the temperature range studied.
