Method for preparing 1, 3-butanediol

The invention provides a method for preparing 1, 3-butanediol. The method comprises the following steps: (1) carrying out condensation cyclization reaction on butadiene, water and an aldehyde ketone compound according to a certain material ratio in the presence of hydrogen peroxide and a catalyst A to obtain a reaction solution containing an intermediate I; and (2) mixing the reaction solution containing the intermediate I with a certain amount of water, and carrying out hydrolysis reaction in the presence of a catalyst B to obtain 1, 3-butanediol and a corresponding aldehyde ketone compound.Compared with the existing production method, the method has the advantages of accessible reaction raw materials, high reaction conversion rate, high selectivity and the like, and is suitable for industrial production.
