| Trioctylphosphine oxide Usage And Synthesis |
| Chemical Properties | white crystalline powder |
| Purification Methods | Mason, McCarty and Peppard [J Inorg Nuclear Chem 24 967 1962] stirred a 0.1M solution in *benzene with an equal volume of 6M HCl at 40o in a sealed flask for 48hours, then washed the *benzene solution successively with water (twice), 5% aqueous Na2CO3 (three times) and water (six times). The *benzene and water were then evaporated under reduced pressure at room temperature. Zingaro and White [J Inorg Nucl Chem 12 315 1960] treated a pet ether solution with aqueous KMnO4 (to oxidise any phosphinous acids to phosphinic acids), then with sodium oxalate, H2SO4 and HCl (to remove any manganese compounds). The pet ether solution was slurried with activated alumina (to remove phosphinic acids), filtered, evaporated and the residue was recrystallised from pet ether or cyclohexane at -20o. It can also be recrystallised from EtOH. [Beilstein 4 IV 3466.] |
