Method for producing .GAMMA.-butyrolactone |
| abstract |
(57) [Summary] [Objective] To provide a method for producing γ-butyrolactone with high yield and high selectivity. A catalyst containing copper, chromium, manganese and / or barium, and sodium and / or potassium, which is 40 ° C. or lower to 100 to 100 ° C. while flowing an inert gas containing 0.1 to 1% by volume of hydrogen. Catalytic dehydrogenation of 1,4-butanediol was carried out in the gas phase in the presence of a catalyst which had been preheated to 140 ° C. and then subjected to a reduction treatment in which the temperature and hydrogen concentration were gradually increased. A method for producing γ-butyrolactone. |
