Synthesis of 1,2-dibromoethane

Preparation of 1,2-dibromoethane

Preparation of 1,2-dibromoethane

Preparation of 1,2-dibromoethane

A fairly rapid stream of ethylene is generated from ethyl alcohol and sulfuric or phosphoric acid. The ethylene gas is washed first with water and then with dilute solution of sodium hydroxide, is passed into 100 g of bromine contained in a glass flask cooled ice-waters. The stream of ethylene gas is continued until the brown color of bromine disappears. The 1,2-dibromoethane forms as  an oily liquid which is washed with dilute solution of sodium hydroxide, dried with calcium chloride. 1,2-dibromoethane is purified by distillation yielding colorless oily liquid, freezing at 8° C and boiling at 131° C.
