METHOD OF PRODUCING PALLADIUM CATALYST FOR HYDROGENATING ACETYLENE Russian patent published in 2016 - IPC B01J37/02 B01J23/44 B01J21/04 C07C5/09 C07C11/04

Abstract RU 2572787 C1

FIELD: chemistry.

SUBSTANCE: catalyst is produced by dissolving a palladium catalyst in supercritical carbon dioxide in the temperature interval of 305-353 K, followed by deposition on an alumina substrate. The palladium complex used is palladium hexafluoroacetylacetonate and dissolution thereof in supercritical carbon dioxide is carried out at pressure of 8-8.5 MPa.

EFFECT: method cuts the time for producing a palladium catalyst to 5 minutes and enables to obtain catalysts characterised by high degree of conversion of acetylene.
