Vorschrift

A 25 g (0.1 mole) amount of p-octyloxybenzoic acid was suspended in 120 ml of water. The temperature was increased to between 50° C. and 55° C. and 17.6 g (0.11 mole) of bromine were added over a period of 7 hours at that temperature. The suspended solids were then filtered and recrystallized from ethanol and pure 4-octyloxy-3-bromobenzoic acid was obtained.
