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.
