Latest Patents

Orito's latest patents include a method for partial nuclear hydrogenation of aromatic hydrocarbons. This invention provides an improvement in the partial nuclear hydrogenation of aromatic hydrocarbon compounds in the liquid phase with an admixture of water, catalyzed by a ruthenium-containing solid catalyst. The innovation lies in the use of a novel ruthenium-containing catalyst supported on a silica gel carrier, which is prepared through the hydrolysis and gelation of an alkoxide of silicon or aluminum in a solution containing a ruthenium compound. This method results in a catalyst that is uniformly impregnated with ruthenium, significantly enhancing its catalytic activity and selectivity compared to conventional methods.

Another significant patent by Orito is a method for the asymmetric hydrogenation of α-ketoesters. This method involves subjecting an α-ketoester containing a specific grouping to asymmetric hydrogenation in the presence of a platinum-alumina catalyst modified with a solution of a cinchona-alkaloid. This innovative approach has implications for the synthesis of chiral compounds in pharmaceuticals.
