Phenylphosphinic acid Chemical Properties,Uses,Production

Chemical Properties

white crystals or crystalline powder


Antioxidant, intermediate for metallic-salt formation, accelerator for organic peroxide catalysts.

Purification Methods

Crystallise it from H2O (solubility is 7.7% at 25o). Also purify it by placing the solid in a flask covered with dry Et2O, and allowed it to stand for 1day with intermittent shaking. Et2O is decanted off and the process repeated. After filtration, excess Et2O is removed in a vacuum. It has also been recrystallised from *C6H6.
