Product Name:ARSENIC (III) BROMIDE
CAS Number:7784-33-0
Molecular formula:AsBr3
Molecular Weight:314.63

A boat is placed in a Pyrex tube and filled with As powder. A stream of dry N3, saturated with Br 3 vapor by passage through a Br2-filled wash bottle, is passed over the As. The tube is inclined toward the receiver and connected with the latter by means of an asbestos-paper-sealed adapter. The tube is heated until the onset of reaction. The product is distilled from the receiver over As powder.
