Abstract

Trans-9, cis-11- octadecadienoic acid is produced by forming a urea inclusion complex with cis-linoleic acid, treating the complex with a catalytic amount of a base, and recovering the trans-9, cis-11 octadecadienoic acid. Tans- 10,cis-12- octadecadienoic acid is produced by iodinating cis- linoleic acid at temperatures of about -5-2O0C. A mixture of trans-9, cis-11 octadecadienoic acid and trans-10, cis-12- octadecadienoic acid comprising is produced by iodinating cis- linoleic acid at temperatures ranging from about 50 to about 900C.
