| | Thionyl bromide Usage And Synthesis |
| Chemical Properties | Orange-yellow liquid. On prolonged standing, slowly decomposes into SO2, Br2 and S2Br2 and turns reddish; very sensitive
to moisture. M.p. -49.5°C. Its thermal stability is poor and
therefore SOBr2 can be distilled only in vacuum. | | Uses | Thionyl Bromide is used in the preparation of carbon nanotube-phosphorylcholine polymer composite used in blood condition. | | Preparation | Reaction of SO2 with Br2 in the presence of PCl3: 64 g. of SO2 is
added to a mixture of 138 g. of PCl3 and 160 g. of Br2 , while the
reactor is cooled. The yield, after fractional distillation, is 180
g. of SOBr2. | | Hazard | Extremely destructive to tissue of mucous membranes, upper respiratory tract, eyes, and skin. Reacts vigorously with acetone to form a lachrymator. Should be handled in a fume hood. | | storage | less stable than thionyl chloride and will slowly decompose, even in a stoppered container. Stable if kept dry, but reacts violently with water. |
