An acyloxylation catalyst is obtained by loading (a) a first component containing at least one element of Groups 8, 9, 10 and 11 of the Periodic Table, (b) a second component containing an element which is at least one element of Groups 8, 9, 10 and 11 of the Periodic Table and which is different from the element of the first component, and (c) a third component containing an element which is a component that produces a precipitation-starting pH below the precipitation-starting pH of the first component and second component and which is different from the elements of the first component and second component, onto (d) a support. A catalyst is obtained that can be used to efficiently carry out acyloxylation for economical production of acyloxylated compounds.
A process for production of an acyloxylation catalyst comprising a step of loading (a) a first component containing at least one element of Groups 8, 9, 10 and 11 of the Periodic Table, (b) a second component containing an element which is at least one element of Groups 8, 9, 10 and 11 of the Periodic Table and which is different from the element of the first component and (c) a third component containing an element which is a component that has a precipitation-starting pH below the precipitation-starting pH of the first component and second component and which is different from the elements of the first component and second component, together, onto (d) a support.
