HETEROPOLY ACID AND/OR HETEROPOLY ACID SALT-SUPPORTED TYPE CATALYST, METHOD FOR PRODUCING THE CATALYST, AND METHOD FOR PRODUCING COMPOUND OBTAINED BY USING THE CATALYST

摘要

PROBLEM TO BE SOLVED: To produce a heteropoly acid and/or heteropoly acid salt-supported type catalyst of higher performance, to provide a method for producing the catalyst, and to provide a method for producing a compound obtained by using the catalyst.;SOLUTION: In the supported type catalyst in which at least one kind selected from the group consisting of the heteropoly acid and/or heteropoly acid salt is supported on a catalyst, the heteropoly acid and/or heteropoly acid salt is allowed to exist in such a manner that the gradient of concentration in the carrier entirely reduces from the surface of the carrier toward the center.;COPYRIGHT: (C)2004,JPO&NCIPI
