Abstract

1,2-Bis(2-oxo-5,5-dimethyl-1,3,2-dioxyphosphacyclohexyl-2-imino)ethane (BODIE) was synthesized and characterized by elemental analysis, mass spectra, infrared spectroscopy and nuclear magnetic resonance. The thermostability of BODIE was measured by thermogravimetric analysis and the melting temperature and the fusion enthalpy of BODIE were determined by using a differential scanning calorimeter. A gravimetric method was applied to measure the solubilities of BODIE in the selected solvents. The solubility data of BODIE in selected organic solvents are well fitted by the modified Apelblat model. Also, the solubility parameter of BODIE was estimated by the Scatchard–Hildebrand model. The results show that these models can satisfactorily reproduce the experimental data.
