N2 - The 2-(6-oxido-6H-dibenz[c,e][1,2]oxaphosphorin-6-yl)-1,4-dihydroxy phenylene (ODOPB) was prepared by the addition reaction between 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and p-benzoquinone. The DOPO was synthesized through a multistep reaction from o-phenylphenol and phosphorus trichloride. The structures and the thermal stability of the compound were characterized by infrared spectroscopy (IR), nuclear magnetic resonance (1H NMR and 31P NMR), mass spectroscopy (MS), elemental analysis, and thermogravimetric analysis (TGA). Using a static analytical method, the solubilities of ODOPB in 2-ethoxyethanol in the temperature range from (293.15 to 367.65) K and in methanol in the temperature range from (293.15 to 322.63) K were determined. The solubilities of ODOPB in acetone, ethanol, and 2-ethoxyethanol + water binary mixtures were also measured for comparison. The solubility data were correlated with an empirical equation.
