| titleOfInvention | Method for producing γ-butyrolactone |
| abstract | An object of the present invention is to improve γ-butyrolactone when γ-butyrolactone is produced by dehydrogenation of 1,4-butanediol in the presence of a catalyst, thereby suppressing deterioration of catalyst over time. The production rate is high, and the formation of reaction by-products is prevented, and γ-butyrolactone is efficiently produced. The present invention relates to a method for producing γ-butyrolactone by dehydrogenation of a raw material 1,4-butanediol in the presence of a catalyst comprising a metal belonging to Groups 8 to 11 of the periodic table, and The concentration of the nitrogen-containing compound in the raw material 1,4-butanediol is set to 0.5 to 15 ppm by weight in terms of a concentration in terms of nitrogen atom. |
