    Description / Table of Contents: The gaschromatographic microreactor technique was used to determine the selectivity of Ni-ZnO catalysts which were prepared by decomposition of the mixed oxalates. While monoalkylcyclopentanes were cracked to a high degree even at 280°-440°, the cyclohexanes were converted to aromatics in good yields at 360°. Increasing the Ni content of the catalysts or further raising the temperatur stimulated the ring cleavage in this case too.
    Notes: Mit Hilfe der gaschromatographischen Mikroreaktor-Technik wurde die Selektivität von Ni-ZnO-Kontakten untersucht, die durch reduzierende Zersetzung der Mischoxalate gewonnen wurden. Die Umwandlung einiger Monoalkylcyclopentane und -hexane zwischen 280° und 440° ergab, daß die Cyclopentane weitgehend gespalten werden. Bei den Cyclohexanen überwiegt bis 360° die Dehydrierung zu Aromaten, wenn der ZnO-Gehalt der Kontakte hoch ist.
