Synthesis of 1-bromododecane

Preparation of 1-bromododecane

Preparation of 1-bromododecane

Preparation of 1-bromododecane

With cooling, 1 mole of the 1-dodecanol is treated first with 0.5 mole of concentrated sulfuric acid and then with 1.25 mole of hydrogen bromide (in the form of the 48%, constant-boiling, acid), and the obtained mixture is boiled for 6 hours under reflux. Then it is steam-distilled and the 1-dodecanol is separated off in the separating funnel. The obtained crude 1-bromododecane is twice shaken carefully with about one-fifth of its volume of cold concentrated sulfuric acid or the same volume of concentrated hydrochloric acid in the separating funnel to dissolve the ether produced as a by-product. Then crude 1-bromododecane is washed with water then it is freed from acid with sodium bicarbonate solution, washed again with water, dried over calcium chloride, and distilled through a 20-cm Vigreux column. The yield of 1-bromododecane is 90%, n20/D 1.458; m.p. −11-−9 °C; b.p. 134-135 °C/6 mm; b.p. 148 °C/16 mm; d=1.038 g/mL at 25 °C.
