The synthesized material was extracted using a separating funnel and diethyl ether as a solvent. The samples were washed in cold and hot water to remove the free acids. The optimal reactive conditions, parameters, and procedures for corn oil epoxidation were followed (50°C, 1200 rpm, 10:1 mol ratio of H2O2 to double bonds, and 0.90:1.0 molar ratio of acetic acid to double bonds) (Figure ).
