Abstract
PURPOSE:A catalyst for the manufacture of carboxylic acid ester haing a high selectivity and a high productivity per unit weight of Pd, prepared by the procedure in which a Pd compound and one or more selected from the compounds of Zr, Mo, Pb, and Bi are supported on a support, then the support is subjected to a reduction treatment, and then iodine or an iodine compound is supported on the support so treated. CONSTITUTION:A Pd compound, which is soluble in a general type solvent for the preparation of catalystes, e.g., water, carboxylic acid, alcohol, etc., and one or more selected from the compounds of Zr, Mo, Pb, and Bi, which are soluble in the same solvents, are impregnated in the form of solution into a support, e.g., activated carbon, silica gel, alumina, etc., and then the solvent in the support is evaporated to dryness for the security of the support of metal compounds. Then they are subjected to a reduction treatment using methanol, HCHO, H2, etc., and then dipped in a solution of an iodine compound for supporting the iodine compound. The catalyst contains 0.01 to 5 g atom weight of Zr, etc., and 0.1 to 5 g atom weight of iodine on the basis of 1 g atom weight of Pd, and is suitable for the manufacture of carboxylic acid in which a conjugate dienes, olefins, or aromatic hydrocarbons are oxidized in the presence of carboxylic acid.
