ZSM－35、ZSM－5及丝光沸石中模板分子TMEDA质子化的研究

Studies on Protonation of Template Molecule Tetramethylethylenediamine Trapped in Zeolite ZSM-35,ZSM-5 and Mordenite

用（１３）Ｃ魔角固体核磁共振及化学分析研究处在高硅沸石ＺＳＭ－３５、ＺＳＭ－５及丝光沸石孔道中模板分子四甲基乙撑二胺（ＴＭＥＤＡ）的质子化。（１３）Ｃ核磁共振谱中δ＝３４～３７ｐｐｍ的共振峰可归属于单端质子化的模板分子。它们有序地分布在上述沸石的主孔道中。质子靠近－ＣＨ３基团，远离－Ｃ２Ｈ４－基团。

The protonation of template molecule of tetramethylethylene-diamine( TMEDA) trapped in the channels of zeolite ZSM-35 , ZSM-5 and mordenite was studied by using (13)C CP MAS NMR and chemical analysis. A resonance peaks at δ=34-37 ppm in ￣(13)C spectra can be assigned to the template molecule of TMEDA with one side protonated,which orderly locates at the main channels. The proton is close to-CH_3 group,and far away from-C2H4-group.
