(57) Abstract: A novel catalyst for producing a carboxylic acid ester from an aldehyde and an alcohol in a single step is provided. SOLUTION: Pd-Pb-X (X = Cr, Fe, Co, Z from aldehyde and alcohol in the presence of molecular oxygen. At least one of n and Ag) -a carboxylic acid ester is produced in a liquid phase using a calcium carbonate catalyst. [Effect] Carboxylic acid ester can be produced with high selectivity from aldehyde and alcohol. |
