    摘要: In a catalyst process involving a conversion reaction for organic compounds, e.g. hydrogenations, the catalyst contains at least one support and at least one metal, and is characterized in that it has particles of an average size greater than approximately 1 nm, and more than 80% of particles, the size of which is comprised in the range Dnull(D.0.2) where D represents the average size of the particles. The catalyst is prepared in a colloidal suspension, in aqueous phase, of the metal oxide or metals to be supported, then depositing this suspension on a support, and optionally reducing the oxide thus supported.

    摘要: 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.
