Synthesis and solubilities of 2,6,7-trioxa-1-phospha bicycle 2,2,2 octane-4-carboxylic acid 1-oxide in Selected Solvents

摘要

A phosphorus-containing flame retardant 2,6,7-trioxa-1-phospha bicycle [2,2,2] octane-4-carboxylic acid 1-oxide (PBCC) was synthesized. The structure and the thermal stability of the compound were characterized by infrared spectroscopy (IR), nuclear magnetic resonance (~1HNMR and ~(13)PNMR), mass spectroscopy (MS), elemental analysis, and thermogravimetric analysis (TGA).Using a static analytical method, the solubilities of PBCC in ethanol in the temperature range from 298.90 to 343.20 K and in water in the temperature range from 298.85 to 363.20 K were determined. The solubilities of PBCC in methanol and acetonitrile were also measured for comparison. The solubility data were correlated with an empirical equation.
