These groups render the compounds outstanding, highly oxidatively stable lubricants.Type: GrantFiled: January 19, 1999Date of Patent: November 16, 1999Assignee: Lambent Technologies IncInventor: Anthony J. O'Lenick, Jr.

Patent number: 5741925Abstract: Vinyl naphthenate monomer mixtures are prepared by transvinylation of naphthenic acid in the presence of a catalyst of a palladium carboxylate complexed with one or more aryl N-containing ligands and distilling the resulting vinyl naphthenate monomers in the presence of the catalyst at pot temperatures exceeding 80.degree. C. The catalyst is stable and can be re-used over several transvinylation reaction runs.Type: GrantFiled: January 13, 1997Date of Patent: April 21, 1998Assignee: Air Products and Chemicals, Inc.Inventors: Chung-Ling Mao, Francis Joseph Waller, Kenneth Merle Kem

Patent number: 5679828Abstract: Some betulinic acid and dihydrobetulinic acid acyl derivatives according to the present invention have been found to have potent anti-HIV activity. Introducing a C.sub.2 -C.sub.20 substituted or unsubstituted acyl group at the C.sub.3 -hydroxy group of betulinic acid and dihydrobetulinic acid produces the corresponding 3-O-acyl derivatives. The compounds of the present invention have the following formulae: ##STR1## where R may be a mono- or dicarboxylacyl group, substituted or unsubstituted, of from about 2 to about 20 carbon atoms, and R' may be hydrogen or a C.sub.2 -C.sub.10 substituted and unsubstituted alkyl or aryl group.Type: GrantFiled: June 5, 1995Date of Patent: October 21, 1997Assignees: Biotech Research Labs, Inc., University of North Carolina at Chapel HillInventors: Kuo-Hsiung Lee, Yoshiki Kashiwada, Fumio Hashimoto, Louis Mark Cosentino, Mark Manak
