Abstract:

The oxidn. of oleic acid and the cleavage of the carbon-carbon bond was achieved using potassium permanganate added to oil in water emulsion. The best emulsifier for the oxidn. and cleavage of the double bond was polyoxyethylene lauryl ether (HLB 16.9) which formed the best emulsion with the smaller droplets. The oxidn. is controlled by parameters affecting emulsion stability. Increasing the concns. of emulsifier or oxidizing agent improves the oleic acid conversion and azelaic acid formation. Poor stirring, low HLB's, high oil phase content and poor emulsion prepn. decrease the yields. [on SciFinder(R)]
