Synthesis of 2-bromoethanol (ethylene bromohydrin)

Preparation of 2-bromoethanol

Ethylene gas is washed and passed into an ice-cold solution of 7.2 g of bromine in 500 ml of water. After complete absorption of the bromine a fresh portion of 7.2 g, equal to the first, is added, with frequent and vigorous agitation, until a total weight of 200 g of bromine has reacted. The lower layer of ethylene dibromide which is formed during the process is separated, washed with water, and dried over sodium sulfate. Yield, 88 g. After neutralizing with the sodium carbonate and saturating the aqueous layer with sodium chloride, the 2-bromoethanol is extracted by shaking twice with 100 ml of ether, dried over sodium sulfate, the ether is removed by evaporation yielding 85 g of bulk of the residual liquid which distills between 145-149° C. 54.4% of the bromine is converted into 2-bromoethanol and 37.5% into ethylene dibromide. The remainder is found as hydrobromic acid.
