Abstract
A method for ozonizing an unsaturated fatty acid or a lower alkyl ester thereof is provided as comprising the steps of: supplying an unsaturated fatty acid or a lower alkyl ester thereof as a thin film stream, and passing a gas containing ozone in oxygen or a mixture of oxygen and air or inert gas in the same direction as the flow direction of said thin film stream, thereby achieving gas-liquid contact between the thin film stream of unsaturated fatty acid or lower alkyl ester thereof and the ozone-containing gas. Also provided is a method for oxidative decomposition of the thus ozonized product by contact with ozone-free oxygen gas or air.
