Reaction Steps

Halogen, e.g., bromine, and a conjugated diene, e.g., butadiene, are reacted in vapor phase, the reacted mass condensed and contacted with alkali metal acetate dissolved or dispersed in an acid, e.g., potassium acetate in glacial acetic acid, thus causing a reaction of formed dibromobutene-2 with the acetate to form diacetoxy-2-butene. The latter is hydrogenated to the corresponding diacetoxylated alkane. The diacetoxy alkane is hydrolyzed to the dihydroxy alkane, e.g., 1,4-butanediol. Alternately, the diacetoxy alkene can be hydrolyzed and the hydrogenation then conducted.
