Process and catalyst for the production of γ-butyrolactones |
| abstract |
Process for the catalytic preparation of γ-butyrolactone having the general formula n by reacting an olefin with the general formula R 1 CHCH 2 , with a carboxylic acid with a general formula R 2 CH 2 COOH, wherein R 1 and R 2 represent the substituent R1 and R2 in the butyrolactone, which reaction is performed in the presence of oxygen in contact with a catalyst comprising manganese and at least one basic metal oxide. |
