Kinetics of a double-bond-shift reaction, hydrogen exchange, and 13 C-label scrambling were monitored in situ by 2 H, 1 H, and 13 C MAS NMR for n-but-1-ene adsorbed on the zeolite ferrierite under batch reactor conditions at 290–373 K. A double-bond-shift reaction, the fastest among the three reactions studied, can be monitored provided that 97% of Brønsted acid sites...
