Abstract:
PROBLEM TO BE SOLVED: To enable the reaction of organic substances in far much higher reaction yield or almost quantitatively with a low metal-content catalyst, by using a specific carrier-supported ruthenium catalyst. SOLUTION: In the presence of (A) a catalyst that is prepared by depositing (A1 ) ruthenium only or together with (A2 ) another metal in groups IB, VIIB or VIIIB on a carrier (A3 ) where the average pore size and BET specific surface area are >=50nm and /g, respectively, the content of A1 is 0.01-30wt.% based on the whole catalyst weight and the surface area ratio of A1 /A3 of
Abstract:
PROBLEM TO BE SOLVED: To provide a method for reacting an organic compound by which the reaction of the organic compound is performed in extremely high yield or nearly complete conversion by using a specific catalyst. SOLUTION: All organic compound of a monomer and a polymer, especially an organic compound having a treatable group by hydrogen such as C-C double bond and C-C triple bond are reacted in the presence of a uniform ruthenium compound or a mixture of two or more kinds thereof deposited on a carrier in situ in the method for reacting an organic compound. The reaction is preferably hydrogenation, dehydrogenation, hydrogenolysis, amination hydrogenation or dehalogenation. The catalyst is the supported catalyst obtained by subjecting a solution of the ruthenium compound or two or more kinds thereof to pass through in the carrier or on the carrier to form the uniform ruthenium compound or mixture of two or more compound thereof deposited on the carrier. The smallest amount of a byproduct or a degrading product is formed during the hydrogenation and the reaction is performed without separation, after- treatment and recycle of the catalyst in the method.
