Title:
METHOD FOR COMMERCIAL PREPARATION OF PREFERRED ISOMERIC FORMS OF ESTER FREE CONJUGATED FATTY ACIDS IN POLYETHER ALCOHOL CONTAINING SOLVENTS
Document Type and Number:
WIPO Patent Application WO2001051597
Kind Code:
A3
Abstract:
Methods for sequential saponification and quantitative isomerization of glyceride oils containing interrupted double bond systems, with alkali in a polyether alcohol solvent to yield soaps with conjugated double bond systems are disclosed. The novel properties of the polyether alcohols allow the removal of water added with the alkali by boiling. The preferred embodiment uses a vegetable oil rich in linoleic acid such as sunflower or safflower oil, potassium hydroxide, phosphoric acid to neutralize the soaps. The reaction forms equal quantities of 9Z,11E-octadecadienoic acid and 10E,12Z-octadecadienoic acids.
