This work showed the results from synthesis of Cr‐ZSM‐5 zeolite and their application as catalyst for oxidative cleavage of double bond in oleic acid. Cr‐ZSM‐5 catalyst was obtained by doping chromium into zeolite lattice of ZSM‐5 zeolite by imregnation. This catalyst showed the high catalytic efficiency for liquid phase oxidation of oleic acid with high conversion of 93 % after 3 hr reaction. Furthermore, the effects of conditions of oxidation such as solvent, tempreature and catalyst loading on efficiency of oleic oxidation were also estimated. The suitable conditions for oxidative cleavage of double bond of oleic acid were found to be temperature of 70°C, reaction time of 3 hrs with catalyst amount of 5 wt% in acetonitrile solvent.
