| 英文摘要 | the acidic properties of ts-1 and silicalite-i zeolites have been investigated by the solid-state mas nmr technique capable of in situ sample pretreatment. as shown by a combination of the p-31 mas nmr and h-1 mas nmr techniques with trimethylphosphine, not only bronsted acid sites but also lewis acid sites exist in the ts-1 zeolites. moreover, ts-1 zeolite is more acidic compared with silicalite-1. the h-1, si-29 mas nmr spectra and the resonance related to bronsted acid species in the p-31 mas nmr spectra demonstrate clearly that the presence of titanium in the framework results in the formation of a new hydroxy group, titanols, which is more acidic than silanols of silicalite-1. the p-31 mas nmr measurements also illustrate convincingly the existence of at least two different lewis acid species on the ts-1 zeolites. the conversion of propylene oxide into methoxypropanol catalyzed by ts-1 or silicalite-i zeolite in methanol solution as a test reaction has also been described. with the increase of titanium in zeolite, ts-1 appears to have a higher activity during the reaction of propylene oxide to methoxypropanol. |
