CATALYST FOR VAPOR-PHASE CATALYTIC OXIDATION OR VAPOR-PHASE CATALYTIC AMMOXIDATION OF PROPANE OR ISOBUTANE

摘要

To be an oxide catalyst containing an oxide represented by the general formula (I) is disclosed:; [Formula I]; (Wherein, X is at least one element selected from the group consisting of Te and Sb; Y is one or more elements selected from the group consisting of Al and W; Z is individually to form an oxide having a rutile structure and at least one element selected from the group consisting of elements, Z element oxide having a rutile structure wherein is used as the source of catalyst for Z; Q is titanium, tin, germanium, lead, tantalum, ruthenium, rhenium, rhodium, iridium , platinum, chromium, manganese, technetium, osmium, iron, arsenic, cerium, cobalt, magnesium, and at least one element selected from the group consisting of nickel and zinc, Q element compound not having a rutile structure as a catalyst for producing Q circle is used; a, b, c, d, e, f and n is the atomic fraction of V, Nb, X, Y, Z, Q and O of the Mo, respectively).; Further, it is a method for producing an unsaturated carboxylic acid or unsaturated rutile initiated using the above-mentioned oxide catalyst.
