Abstract:

Different oxidizing agents for performing the cleavage oxidn. of the double bond of the unsatd. fatty acids are presented, and their economic performance is analyzed. Ozone and sodium hypochlorite are the most com. efficient oxidants. Lab. work for the oxidn. of oleic acid to azelaic and pelargonic acids using hypochlorite as oxidant is described. The advantages of working in an emulsion system and using RuCl3 as a catalyst are discussed, and a possible mechanism of the reaction is presented. A flow sheet for an industrial process based on this concept is proposed. A simulation of a plant using this technol. is made by a computerized model, and the economic parameters obtained suggest that sodium hypochlorite can be an interesting reagent for industrial oxidns. of double bonds in fatty acids.
