Abstract
Butanediol and/or butenediol are prepared by hydrolyzing diacetoxybutane and/or diacetoxybutene in the presence of a cation-exchange resin and recovered by fractional distillation. By the treatment of the hydrolyzed product with an anion exchange resin at any stage before the butanediol and/or butenediol are fractionated, butanediol and/or butenediol are recovered in high yield.
