| | PHENYLSELENOL Usage And Synthesis |
| Chemical Properties | clear yellow liquid | | Purification Methods | Dissolve it in aqueous N NaOH, acidify this with conc HCl and extract with Et2O, dry over CaCl2, filter, evaporate on a steam bath and distil the residue from a Claisen flask or through a short column collecting the middle fraction, and seal immediately in a glass vial, otherwise the colourless liquid becomes yellow. The alkali insoluble materials consist of diphenylselenide (b 167o/16mm) and diphenyldiselenide, m 63o (from EtOH). TOXIC, use rubber gloves. It has a foul odour.
