Abstract: A process for production of a supported catalyst that, when used for production of lower aliphatic carboxylic acids from oxygen and lower olefins, improves yields of the lower aliphatic carboxylic acids and minimizes production of carbon dioxide gas (CO2) by-product compared to the prior art. A compound comprising 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 a chloroauric acid salt, are loaded on a carrier, after which there are further loaded a compound comprising at least one element selected from gallium, indium, thallium, germanium, tin, lead, phosphorus, arsenic, antimony, bismuth, sulfur, selenium, tellurium and polonium, and a heteropoly acid.

Abstract: Supported catalysts which allow shortening of the production steps for supported catalysts useful for production of lower aliphatic carboxylic acids from lower olefins and oxygen, and which compared to supported catalysts of the prior art, can inhibit generation of carbon dioxide (CO2) gas by-product during the production of lower aliphatic carboxylic acids. A compound containing at least one element selected from Group 8, 9 and 10 elements of the Periodic Table is loaded on a carrier and then, before reduction treatment of the compound, it is subjected to alkali treatment with an alkaline substance, and a compound containing at least one element selected from gallium, indium, thallium, germanium, tin, lead, phosphorus, arsenic, antimony, bismuth, sulfur, selenium, tellurium and polonium is loaded.
