| titleOfInvention | Method for preparing carboxylic acids by palladium carbonylation |
| abstract | The present invention relates to a process for the preparation of acids carboxylic b ~ ta, gamma unsatur ~ s or satur ~ s. It concerns more particularly the hydroxycarbonylation of an organic compound comprising a conjugated unsaturation, such as butadi ~ ne, by the action of carbon monoxide and water in the presence of a catalyst based on palladium. Acids carboxylic thus obtained are pr ~ f ~ rence, pent ~ no ~ ques acids. according to the invention, the reaction medium after the end of the stage of hydroxycarbonylation is treated ~ by hydrogen ~ ne to reduce palladium has ~ 2 + oxidation state in palladium ~ z ~ ro and r oxidation state ~ cup ~ r palladium pr ~ cipit ~. |
