Mix 40 g. (51 ml.) of isopropyl alcohol with 460 g. (310 ml.) of constant
boiling point hydrobromic acid in a 500 ml. distilling flask, attach a double
surface (or long Liebig) condenser and distil slowly (1-2 drops per second)
until about half of the liquid has passed over. Separate the lower alkyl
bromide layer (70 g.), and redistil the aqueous layer when a further 7 g.
of the crude bromide will be obtained (1). Shake the crude bromide in
a separatory funnel successively with an equal volume of concentrated
hydrochloric acid (2), water, 5 per cent, sodium bicarbonate solution,
and water, and dry with anhydrous calcium chloride. Distil from a
100 ml. flask ; the isopropyl bromide passes over constantly at 59°. The
yield is 66 g.
