The present invention discloses a process for the oxidation of fatty acids comprises reacting fatty acid with O.sub.2 containing O.sub.3 for a period of 0.1-60 min at a temp in the range of −78 to 30 deg C. to obtain the corresponding products, wherein the conversion of the fatty acid is in the range of 80% to 100% and the process is catalyst free and co-oxidant free.

This disclosure provides methods for the chemical modification of triglycerides that are highly enriched in specific fatty acids and subsequent use thereof for producing functionally versatile polymers.

A process of generating an alkyl ester of a fatty acid (e.g., a biodiesel) from a free fatty acid-containing substance (e.g., a feedstock), is provided. The process is effected by contacting a mixture of the free fatty acid-containing substance and a respective alcohol with Lewis Acid; and, while contacting, exposing the mixture and the Lewis acid to ultrasound energy. An alkyl ester of a fatty acid, or a mixture of two or more alkyl esters of fatty acids, (e.g., a biodiesel), obtainable by the process, are also provided.

Provided is a free-polyunsaturated-fatty-acid-containing composition that has a total metal content of 0.1 ppm or less and that comprises at least one free polyunsaturated fatty acid having 20 or more carbon atoms, in an amount that is at least 80.0% of the amount of fatty acids in the composition; and a method for manufacturing a free-polyunsaturated-fatty-acid-containing composition, comprising: providing a raw material composition containing at least one polyunsaturated fatty acid having 20 or more carbon atoms; performing a hydrolysis treatment on a reaction solution prepared by combining the provided raw material composition, a lower alcohol, water having a total metal content of 0.01 ppm or less, and an alkali catalyst; and limiting the contact between the reaction composition and the metal after the hydrolysis treatment so that the product T [cm.sup.2×days] of the contact surface area [cm.sup.2] per 1 g and the contact time [days] between the composition and the metal is 100 or less.
