PROBLEM TO BE SOLVED: To provide a method for producing butene derivatives at high yield and low cost under mild reaction conditions. SOLUTION: 3-hydroxy-4-acetoxy-1-butene (hereinafter abbreviated as 3,4-HABE) and / or 3-acetoxy-4-hydroxy-1-butene (hereinafter abbreviated as 3,4-AHBE). ) And acetic anhydride to produce 3,4-diacetoxy-1-butene (hereinafter abbreviated as 3,4-DABE), which comprises 3,4-HABE and / or 3,4-HAH and / or 3,4-HAH and / or 3,4-HAH are obtained from a reaction product obtained by subjecting 1,3-butadiene and acetic acid to an acetoxylation reaction in the presence of molecular oxygen and a palladium-based catalyst. A method for producing 3,4-DABE, which is obtained by separating a mixture containing AHBE by distillation. [Selection] Figure 1 |
