BISMUTH(III) IODIDE synthesis

4synthesis methods
Iodine (20 g.) is ground with 45 g. of finely powdered Bi in a mortar and then rapidly placed in a retort. The mixture is heated until reaction begins. At the end of the reaction, a stream of CO3 is passed through the warm retort to remove unreacted iodine. The iodide is then sublimed in a stream of CO3. Smaller quantities can also be prepared by placing the mixture in a boat inserted into a Vycor tube, heating, and then subliming the Bil 3 in a CO3 stream.
