(57) [Summary] [Object] To provide a method for producing γ-butyrolactone with high yield and high selectivity by oxidative dehydrogenation of 1,4-butanediol under mild conditions. [Structure] When γ-butyrolactone is produced by the oxidative dehydrogenation of 1,4-butanediol in the presence of molecular oxygen, a catalyst containing platinum and a bismuth compound is used. |
