Abstract

original image

Es gehören zwei dazu: Ein hoher Konversionsgrad für den Einbau der 13C-Atome von Methan in die Produkte einer Methan/Propan-Coaromatisierung am Zeolith Zn/H-BEA wurde durch 13C-Festkörper-NMR-Spektroskopie und GC-MS nachgewiesen. Isotopenmarkierungsexperimente zum Mechanismus ergaben, dass zunächst aus Propan gebildete aromatische Spezies methyliert werden, worauf eine Ringexpansion/-kontraktion folgt (siehe Schema).
