| Hazard Information | Back Directory | [Chemical Properties]
dark red liquid; decomposes if heated in moist air [MER06] | [Production Methods]
A round-bottom flask, equipped with a separatory funnel and gas outlet tube connected to a P2O5 drying tube, is filled with a suspension of 20 g of pure powdered Se in 50 ml of dry CS2; 20 g of pure Br2 is then slowly added from the separatory funnel. If the flask is occasionally shaken, the reaction is soon complete. A reddish-brown solution is formed, from which the CS2 is evaporated in a vacuum as rapidly as possible. The product is deep-red, pure Se2Br2.
