A novel production of carboxylic acid ester, where aldehyde and alcohol are reacted in liquid phase in the presence of molecular oxygen, uses catalysts composed of calcium carbonate supported Pd and Bi, and one or more of the elements of Ba, Fe, Zn, and Ge. Also claimed is another production of carboxylic acid ester, where aldehyde and alcohol are reacted, using catalysts composed of calcium carbonate-supported Pd, Bi, and Pb, with Ba, Fe, Zn and/or Ge. |
