 Title    Nitrogen-15 and Boron-11 NMR Spectroscopy of the System Acetonitrile / H-ZSM-5  
 Abstract    The interaction of adsorbed acetonitrile with microporous [Si,Al]-ZSM -5 and [Si,B]-ZSM-5 was investigated by solid state NMR. l:iN-CP MAS NM R of the system H-[Si,Al]-ZSM -5 / acetonitrile clearly shows the Bronsted and Lewis acid site interactions. Different coordina­ tion types of the complex ZSM-5/MeCN are considered. The accessibility o f the acid sites of [Si,B]-ZSM -5, a material structurally analogous to zeolite ZSM-5, was studied by " B-M AS NM R. The com plexation o f acetonitrile at the BO^ sites gives a narrow line at -4 ppm. In contrast to hydration phenomena of ZSM-5, the experiments show that acetonitrile is not capable of interacting with all of the BO 3 sites of the borosilicate, presumably due to steric effects.
