Process for making high-purity oleic acid

An oleic acid containing adduct is produced by reacting tall oil fatty acid (which contains pre-conjugated linoleic acid) with a dienophile at a temperature between 180 DEG C. and 300 DEG C. No catalyst or solvent is necessary for the reaction to occur. The adduct is subsequently distilled to yield...

Summary:An oleic acid containing adduct is produced by reacting tall oil fatty acid (which contains pre-conjugated linoleic acid) with a dienophile at a temperature between 180 DEG C. and 300 DEG C. No catalyst or solvent is necessary for the reaction to occur. The adduct is subsequently distilled to yield a high-purity, light color oleic acid.
