CAS databases provide millions of journal article references from more than 10,000 major scientific journals worldwide, patent and patent family references from 61 patent authorities around the world, and other reputable web sources.

The following patent record is from the CAplusSM database.

CAPLUS COPYRIGHT 2011 ACS
Patent Number: WO 2004062763 (basic equivalent for US 7960599)
Title: Synthesis of industrial chemicals by isomerization of fatty acids using ruthenium-based catalysts
Inventor(s): Millis, James R.; Tupy, Michael J.; Abraham, Timothy W.; De Souza, Mervyn L.
Patent Assignee(s): Cargill, Incorporated, USA
Source: PCT Int. Appl., 32 pp. CODEN: PIXXD2
Language: English

Abstract:
The unsatd. site of a precursor, such as unsatd. fatty acids and fatty acids derived from soybean oil, can be  isomerized by enzyme to receive an isomerized derivative, and then reacted with an unsatd. compound, such as ethylene, in the presence of a ruthenium-based metathesis catalyst to prepare industrial chems., such as butadiene, 1-octene, and 9- decenoic acid. Thus, linoleic acid derived from soybean oil was isomerized by lactobacillus reuteri to obtain delta-9,11-conjugated linoleic acid, which can esterify by methanol to provide Me-delta-9,11-octadecadienoate.

Please note: The titles for patent records in CAplus are routinely enhanced to better describe the claimed invention. In this example, the original title of both the U.S. equivalent and the PCT is Method for making industrial chemicals. This title was enhanced to read Synthesis of industrial chemicals by isomerization of fatty acids using ruthenium-based catalysts. CAS originally indexed the PCT publication (WO 2004062763) as the first published record of the invention which was assigned to Cargill Inc. It was subsequently reassigned on 20080506 to Elevance Renewable Sciences, Inc. which is what is shown on the granted patent US 7960599 published on 20110614.
