PROBLEM TO BE SOLVED: To provide a method for producing 3-butene-2-ol and 1,3-butadiene from 2, 3-butanediol at a high selectivity without using radioactive substances.SOLUTION: Provided is a method for producing 3-butene-2-ol in which 2, 3-butanediol is dewatered using at least one kind selected from a group consisting of zirconium oxide, a zirconium oxide-alkali metal compound complex and zirconium-alkaline-earth metallic compound complex as a catalyst. 【課題】放射性物質を使わず、高い選択率で、２，３−ブタンジオールから３−ブテン−２−オール及び１，３−ブタジエンを製造する方法を提供すること。【解決手段】３−ブテン−２−オールの製造方法は、酸化ジルコニウム、酸化ジルコニウム−アルカリ金属化合物複合体及び酸化ジルコニウム−アルカリ土類金属化合物複合体から成る群より選ばれる少なくとも１種を触媒として用いて、２，３−ブタンジオールを脱水することを含む。【選択図】図１
