PROCESS FOR PRODUCING alpha,beta-UNSATURATED CARBOXYLIC ACID |
| 摘要 |
<p>A process for producing an alpha,beta-unsaturated carboxylic acid with higher selectivity. The process comprises producing an alpha,beta-unsaturated carboxylic acid from an olefin or an alpha,beta-unsaturated aldehyde in a liquid phase using a catalyst containing a noble metal, and is characterized by causing a compound (A) having an acid dissociation constant (pKa) less than 4 to be present in the liquid phase.</p> |
