Synthesis of Mesoporous AlTS-1 using Carbon Template and Catalytic Beckmann Rearrangement Reaction |
| 초록 |
A series of mesoporous aluminium titanium ailicalite-1(AlTS-1) was prepared through the microwave synthesis by varying the amounts of nanosized carbon template. The N2 adsorption and desorption analyses of the obtained materials showed the presence of both mesoporosity and microporosity. The acid sites of mesoporous AlTS-1 materials depending on the types of pores were investigated with conventional AlTS-1 zeolites by in-situ FT/IR spectroscopy for the adsorption of pyridine. The increases in mesoporosity of materials were found as the carbon contents increased in both microwave and hydrothermal synthesis. The dependency of Lewis and Brönsted acidity on carbon contents were more evident in the case of microwave synthesis due to the role of carbon as microwave absorption sites. The MFI structured AlTS-1 zeolite performed well for the vapor phase Beckmann rearrangement of cyclohexanone oxime into caprolactam. |
