| Phenylphosphonic acid Usage And Synthesis |
| 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.
