METHOD FOR THE CATALYTIC HYDROGENATION OF AROMATIC OR HETEROAROMATIC AMINES |
摘要 |
<p>A process for the catalytic hydrogenation of an organic compound, in particular a labile organic compound, in the presence of a support catalyst with a coating containing ruthenium as active metal and a total of 1.01 to 30 wt. % of active metals. Higher stereoselectivity and a greater catalyst shelf life may be obtained by using a support catalyst of which the oxide, carbide, nitride or siliceous support material has a BET (N2) surface area smaller than 10 m2/g, particularly preferably 0.1 to 5 m2/g, prior to loading with at least one active metal diatomaceous earth with a BET (N2) surface area greater than 2 m2/g is excluded and the ruthenium content thereof makes up at least 50 wt. %, preferably at least 99 wt. % of the active metals. The process and the catalysts are particularly suitable for the hydrogenation of polyfunctional compounds such as hydroxycarbonyl compounds and aromatic amines.</p> |
