Phenylphosphinic acid MSDS


Benzenephosphinic acid

Phenylphosphinic acid C??? ??, ??, ??

??? ??

white crystals or crystalline powder

??

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

?? ??

Phenylphosphinic acid is also known as phenylphosphonous acid. Kinetics of oxidation of phenylphosphinic acid by metal and non metal oxidants was investigated in a study.2

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.
