This work describes two sustainable methods for prodn. and purifn. of azelaic acid (AA) to replace the current process of ozonolysis of oleic acid (OA)​. The first proceeds in two steps, coupling smooth oxidn. of OA to 9,​10-​dihydroxystearic acid (DSA) with subsequent oxidative cleavage by sodium hypochlorite. An alternative methodol. is also proposed, using a chemocatalytic system consisting of H2O2/H2WO4 for direct oxidative cleavage of the double bond of OA at 373 K.

Abstract

This work describes two sustainable methods for prodn. and purifn. of azelaic acid (AA) to replace the current process of ozonolysis of oleic acid (OA)​. The first proceeds in two steps, coupling smooth oxidn. of OA to 9,​10-​dihydroxystearic acid (DSA) with subsequent oxidative cleavage by sodium hypochlorite. An alternative methodol. is also proposed, using a chemocatalytic system consisting of H2O2/H2WO4 for direct oxidative cleavage of the double bond of OA at 373 K. A convenient technique for sepn. and purifn. of azelaic acid is also proposed.
