Thionyl bromide Chemical Properties, Uses, Production
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.
