production method | 1. note that it is highly toxic and should be carefully operated in a ventilated kitchen and wearing rubber gloves. In 40 ml of carbon tetrachloride, pure 0.496g of biphenyl selenium is added, and 2.92 moles of ozone are absorbed at a 5 ℃. The solvent is distilled under reduced pressure to get 0.57 grams of phenylselenite drunk. You can also heat phenylselenite together with a theoretical amount of water in a vacuum at 140 ℃ for 1 hour, or in a vacuum at 90 ℃ for 2 hours to obtain a crude product. |
