Phenylphosphonic acid Chemical Properties,Usage,Production

Chemical Properties

white to off-white crystalline powder

Uses

Intermediate in antifouling paint agents; catalyst in organic reactions.

Uses

Phenylphosphonic acid additive used with Noyori's catalyst for oxidation of sulfides to sulfones. Used as additive of unsaturated polyester PU resin. It also can be added into nylon to improve its polymerization degree. It can be used as extreme pressure agent of lube; used as catalyst of carboxylic acid & alcohol reaction; it can be used as fire retarding treatment of fiber used asganic materials.

Definition

ChEBI: Phenylphosphonic acid is a member of benzenes.

Hazard

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.]
