Abstract

Crude diarylphosphine oxides are purified by reacting with a lower (C1-C3 alkyl ketone, isolating the diaryl 2-hydroxy-isoalkyl phosphine oxide so formed, and heating said diaryl 2-hydroxyisoalkyl phosphine oxide in the absence of oxygen and moisture to regenerate the pure diarylphosphine oxide. The diaryl 2-hydroxyisoalkyl phosphine oxide may be purified itself, e.g. by washing or crystallisation. In an example, diphenylphosphine oxide is reacted with acetone to give diphenyl 2-hydroxyisopropyl phosphine oxide. Specifications 938,893 and 938,894 are referred to.
