    • PROBLEM TO BE SOLVED: To provide a method for producing from alcohol having at least a primary hydroxyl group and a secondary hydroxyl group a corresponding ketol compound selectively at a high yield using a heterogeneous catalyst capable of being easily separated and recovered from a reaction product and being reused.SOLUTION: In a method for producing a ketol compound, alcohol having at least a primary hydroxyl group and a secondary hydroxyl group is oxidized in the presence of a copper catalyst supported on a carrier to produce a corresponding ketol compound. Glycerol is preferable as the alcohol having at least a primary hydroxyl group and a secondary hydroxyl group, and dihydroxyacetone is preferable as the corresponding ketol compound.
    • 要解决的问题:提供一种使用能够容易地从反应产物中分离和回收的多相催化剂以高产率选择性地生产具有至少伯羟基和仲羟基的醇的相应酮醇化合物的方法,以及 在一种制备酮醇化合物的方法中,在负载在载体上的铜催化剂存在下,将至少具有伯羟基和仲羟基的醇氧化,生成相应的酮醇化合物。 优选甘油作为至少具有伯羟基和仲羟基的醇,二羟基丙酮作为相应的酮醇化合物是优选的。
