PURPOSE:To provide a method for producing 7-butyrolactone in high yield and selectivity with suppressed formation of by-products. CONSTITUTION:The subject method for producing gamma-butyrolactone is to catalytically dehydrogenate 1,4-butanediol in the vapor phase in the presence of a catalyst containing copper, chromium, manganese and/or barium and sodium and/or potassium. |
