METHOD FOR CATALYTIC HYDROGENATION REACTION USING PALLADIUM CARRIED BY SILICA GEL WITH DUAL PORE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently carrying out catalytic hydrogenation reaction of a site to be hydrogenated without problems of difficulty in handling, e.g. the danger of ignition, possessed by a conventionally used palladium-carbon catalyst.;SOLUTION: This method for carrying out the hydrogenation reaction of the site to be hydrogenated involves bringing a compound having the site to be hydrogenated into contact with hydrogen gas in the presence of the palladium carried by the silica gel with the dual pore system comprising macro pores having 0.5-25 μm pore diameters and mesopores having 5-25 nm pore diameters.;COPYRIGHT: (C)2004,JPO&NCIPI
