Latest Patents

One of his latest patents is the "Process for preparing tertiary amines." This innovative method involves reacting a long-chain olefin with carbon monoxide, hydrogen, and a primary or secondary amine in the presence of a catalyst composed of a rhodium- and/or ruthenium-containing compound using a specific solvent. The process also includes phase separation of the reaction product, which facilitates the recovery and re-use of the expensive catalysts.

Another significant patent is the "Process for producing polycyclic diols." This process entails the hydroformylation of a polycyclic bridged ring olefinic compound that has another double bond, formyl, or methylol group. It is conducted in the presence of a cobalt compound and a phosphine as a catalyst, along with a saturated hydrocarbon or aromatic hydrocarbon. Polycyclic diols, such as tricyclodecanedimethylol, produced through this method are useful for hardeners in non-solvent type lacquers, polyurethanes with heat resistance, and chemical resistance, or epoxy resins.
