METHOD FOR SELECTIVE HYDROGENATION OF UNSATURATED ALDEHYDES Russian patent published in 2017 - IPC C07C45/62 C07C47/02

Abstract RU 2626958 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method for producing saturated aldehydes by contacting a liquid organic feed containing unsaturated aldehydes with hydrogen or hydrogen-containing gas in presence of crustal catalyst comprising palladium particles of not more than 6 nm in size, applied in form of a layer not thicker than 150 microns on exterior surface of porous alumina carrier granules. Herewith the carrier has not less than 60% of pores with a diameter of 5 to 50 nm, and the hydrogenation is carried out at a liquid feed rate of 1-4 h^-1.

EFFECT: producing target products with high selectivity at high process efficiency and feedstock conversion.
