ABSTRACT

Methyldiphenylphosphine oxide (MDPPO) was characterized by infrared spectroscopy (IR), nuclear magnetic resonance (1H NMR and 31P NMR), and a differential scanning calorimeter (DSC). Using a static analytical method, the solubilities of MDPPO were measured in benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, ethyl acetate, and binary solvent mixtures: acetone + n-hexane (volume ratio = 3:7) and benzene + ethyl acetate (volume ratio = 1:1). The experimental results were correlated with an empirical equation. The estimated uncertainty of all the solubility values was within 2.0 %.
