Diphenyl phosphate Usage And Synthesis
| Chemical Properties | white crystalline powder |
| Uses | Diphenyl phosphate can be used as an organic catalyst for the ring-opening polymerization (ROP) of renewable 5-alkyl δ-lactones. In combination with zinc iodide, it forms a novel initiating system for the living cationic polymerization of isobutyl vinyl ether. |
| Definition | ChEBI: Diphenyl phosphate is an aryl phosphate and metabolite of the flame retardant Triphenyl Phosphate and also a metabolite of 2-Ethylhexyl diphenyl phosphate. |
| Purification Methods | Crystallise it from CHCl3/pet ether. [Cherbuliez in Organo Phosphorus Compounds (Kosolapoff & Maier eds) Wiley Vol 6 pp 211-577 1973, Beilstein 6 IV 714.] |
| Toxics Screening Level | The initial threshold screening level (ITSL) for diphenyl phosphoric acid is 0.1 μg/m3 based on annual averaging time. |
