ABSTRACT:
A supported catalyst comprising a support having supported thereon at least one member selected from the group consisting of heteropolyacids and heteropolyacid salts, in which the heteropolyacid and/or heteropolyacid salt is substantially present in a surface layer region of the support to a depth of 30% from the support surface. The catalyst has a high performance when used for the production of compounds by various reactions.
