Abstract

Catalytic oxidation of oleic acid with ozone gas by using ozone-generator and solvent free medium in the presence of WO3-Polypyrrole (ppy) nanocomposite was studied. Azelaic acid (AA) and pelargonic acids (PA) are the major reaction products, however the percentage of AA production is significantly higher than PA. Experimental results concluded that tungsten oxide and tungten oxide on polypyrrole are suitable catalysts in terms of their selectivity and activity. Reaction is done in two steps within 90 minute, showing the reasonable promotion in selectivity to AA by using WO3-ppy catalyst system compared to reaction with WO3 as catalyst. WO3-ppy nanocomposite is prepared by sonication method and characterized by FT-IR, XRD, and FESEM analysis. The products of ozonolysis are identified by GC-FID and GC-MS for measuring selectivity and reactivity as well.
