摘要
有机物的吸附，如2,4-戊二酮和甲苯，在高硅MCM-22的29Si MAS NMR谱中引起明显的可逆变化，这些变化具有局部几何扰动的特征。这些细微的光谱特征进一步证实了在MCM-22框架中存在改良的十二烷基- 1h笼。
Sorbate-induced changes in the 29Si MAS NMR spectrum of highly siliceous MCM-22
Sorption of organics, such as 2,4-pentanedione and toluene, cause distinct and reversible changes in the 29Si MAS NMR spectrum of highly siliceous MCM-22 that are characteristic of perturbations in local geometry. These subtle spectral features further substantiate the presence of the modified dodecasil-1H cage in the MCM-22 framework.
