Patent number: 8765975Abstract: This invention provides a process for producing dihydronepetalactone using mixtures comprising both trans-cis nepetalactone and cis-trans nepetalactone. A reaction mixture comprising trans-cis nepetalactone and cis-trans nepetalactone is first contacted with hydrogen in the presence of at least one hydrogenation catalyst under conditions that optimise the preferential conversion of trans-cis nepetalactone to dihydronepetalactone. Cis-trans nepetalactone is subsequently converted to dihydronepetalactone by contact with hydrogen in the presence of at least one hydrogenation catalyst.Type: GrantFiled: December 20, 2007Date of Patent: July 1, 2014Assignee: E I du Pont de Nemours and CompanyInventors: Keith W. Hutchenson, Scott Christopher Jackson, Leo Ernest Manzer, Mark A. Scialdone, Mayis Seapan
