Abstract
A method for preparing triglyceride oils containing at least 2% branching on the hydrocarbon chain, said method involving subjecting in a pressurized container (a) a feedstock containing unsaturated fatty acids attached to a glycerol backbone having 6 to 25 carbon atoms or mixtures thereof, (b) modified zeolite, and (c) water or alcohol in the presence of an inert atmosphere (e.g., at a temperature of about 150° C. to about 350° C. and a pressure of about 10 to about 300 psi for about 24 to about 72 hours) to produce triglycerides containing at least 2% branching (and optionally isolating said triglycerides containing at least 2% branching and optionally purifying the isolated triglycerides containing at least 2% branching); wherein said modified zeolite has been calcined at about 760° C. to about 840° C. for about 20 to about 28 hours, then placed in about 1N HCl at about 50° C. to about 60° C. for about 20 to about 28 hours and washed with water until the pH is neutral.
