With a total of 2 patents, Nagamura's work has garnered attention for its innovative approaches and methodologies.
Latest Patents
Nagamura's latest patents include a producing method of alcohols such as cyclohexanedimethanol. This method involves obtaining a benzyl ester through the reaction between a benzyl compound and carboxylic acid in the presence of oxygen and a catalyst. The catalyst comprises palladium, gold ultra-fine particles, and at least one element selected from Groups IIA, IIIA, VIA, IIB, VB, and VIII of the periodic table, along with alkali metals. The alcohols are produced by hydrogenating the benzene ring of the benzyl ester and subsequently hydrolyzing the resultant esters. Alternatively, the benzyl ester can be hydrolyzed to produce benzyl alcohols, which are then hydrogenated to yield the desired alcohols. Another notable patent is for a catalyst for oxidizing methylbenzenes and a method for producing aromatic aldehyde.
