When used to prepare lower aliphatic carboxylic acids from oxygen and lower olefins, supported catalysts that improve the yield of lower aliphatic carboxylic acids and also minimize the production of by-product carbon dioxide gas (CO 2 ) compared to the prior art. It provides a method of manufacturing. Compounds containing at least one element selected from elements of Groups 8, 9 and 10 of the periodic table, at least one chloride of an element selected from copper, silver and zinc, and chloroaurate are then supported on the carrier, followed by gallium, indium Further carrying a compound containing at least one element selected from thallium, germanium, tin, lead, phosphorus, arsenic, antimony, bismuth, sulfur, selenium, tellurium and polonium, and heteropolyacids. n n A method for producing a supported catalyst for producing acetic acid. |
