Phenylphosphonic acid Chemical Properties,Uses,Production

Chemical Properties

white to off-white crystalline powder


Intermediate in antifouling paint agents; catalyst in organic reactions.


Highly toxic.

Purification Methods

It is best to recrystallise it from H2O by concentrating an aqueous solution to a small volume and allowing to crystallise. Wash the crystals with ice cold H2O and dry them in a vacuum desiccator over H2SO4. [Lecher et al. J Am Chem Soc 76 1045 1954.] pK2 5 values in H2O are 7.07, and in 50% EtOH 8.26. [Jaffé et al. J Am Chem Soc 75 2209 1953, IR: Daasch & Smith Anal Chem 23 853 1951, Beilstein 16 IV 1068.]
