| 제목 | Meso TiO2 treated different calcination temperature as catalyst for epoxidation of 1-octene with hydrogen peroxide |
| 초록 | Epoxides are well known as one of the most valuable building blocks, which can be used as intermediates for chemicals production. From an industrial point of view, The epoxidation of alkene has recevied the great attention. Until now, epoxides are produced by a large peracid as oxidant. However, peracid has many disadvantages such as expensive, hazardous, and acid waste. So hydrogen peroxide is an ideal oxidant for epoxidation of 1-octene because of its ease of handling and high activity as oxidant, as well as the fact that byproduct is natural product, namely water. In this study, to develop catalysts for the epoxidation, the epoxidation reaction of the 1-octene and H2O2 as oxidant were carried out. A series of meso-TiO2 that treated different calcination temperature from 200 oC to 700 oC were successfully synthesized. The properties of as-prepared catalyts were characterized by X-ray diffraction, N2 - sorption, scanning electron microscope. These catalysts show different epoxidation activities for 2 hours. In particular, meso-TiO2 300 oC exhibits best catalytic activitiy than other catalysts. |
