    摘要: A method for producing ozone for use in ozonolysis reactions. Oxygen is separated from the mixture of ozone and oxygen from an ozone generation unit and is fed back to the oxygen feed to the generation unit. Nitrogen is fed to the ozone separation unit and the mixture of nitrogen and ozone is fed to the ozonation reactor where the ozone will react with organic compounds to produce desired end products.

    摘要: 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.
