Synthesis of biologically active linoleic acid isomers with use of oxide catalyst
Grape seed oil was treated with KOH or CaO in (HOCH(2))(2) or glycerol at 185 C for 3 h to isomerize the 9c,12cC18:2-linoleic acid to its conjugated diene 9c,11tC18:2 and 10t,12cC18:2 isomers. CaO was more less active than KOH as the isomerization catalyst, but the Ca salts are of higher practical use.
