Process for the preparation of cyclohexane-1,3-dione from delta-ketocarboxylic acid esters |
| abstract |
Cyclohexane-1,3-diones are prepared by reacting δ-ketocarboxylic acid esters in the gas phase at temperatures of 250 ° C to 500 ° C on a catalyst. The catalyst contains at least one element from Group IIIB or IVB of the periodic table in the form of a compound. Particularly preferred catalysts are thorium compounds on carbon supports. |
