Cyclohexene oxide is an epoxide that serves as a valuable intermediate used in the petroleum and chemical industry. The main production problem of cyclohexene oxide is the formation of undesired products, which are produced by side reactions, such as 2-cyclohexene-1-ol, 2-cyclohexene-1-one, trans-1, 2-cyclohexanediol, and others. The aim of this research is to optimize cyclohexene epoxidation reaction over mesoporous-assembled CeO2-TiO2 catalyst. The catalyst used is synthesized by a single-step sol-gel method. Hydrogen peroxide (H2O2) is chosen as the oxidizing agent. The reaction site for cyclohexene epoxidation is believed to be the surface hydroxyls, as they open up free radicals or act as adsorption centers for the reaction. The products obtained from the reaction are characterized by gas chromatography equipped with a flame ionization detector (GC-FID). Furthermore, several techniques will we use, such as surface area analysis (BET), temperature programmed oxidation (TPO), and thermogravimetric differential thermal analysis (TG-DTA), transmission electron microscopy (TEM) and x-ray diffraction (XRD).
