Chemistry and morphology of coal liquefaction. Quarterly report, January 1, 1986-March 31, 1986. [1,2,3,4 tetrahydroquinoline, 2-propylaniline, quinoline cyclohexylamine and propylbenzene]
Having recently discovered that polynuclear heteroaromatic nitrogen compounds can be selectively reduced only at the nitrogen containing ring, we have now turned our attention towards the cleavage of the carbon nitrogen bonds in this reduced ring. Highlights for this reporting period are: (1) Studies with the 50% nickel oxide catalyst clearly show that 1,2,3,4-tetrahydroquinoline(THQ) provides approximately 20% more liquid product that does quinoline. Thus a first step selective hydrogenation to 1,2,3,4-THQ would enhance the overall HDN reaction to provide a more substantial conversion to substituted benzene and aniline derivatives. (2) The dramatic effect of the nitrogen atom is to inhibit aromatic ring hydrogenation and, to some extent, carbon-carbon bond hydrogenolysis reactivity. This is shown with proplybenzene as the substrate, where only methane gas is produced in the HDN reaction with the 50% nickel oxide catalyst. (3) The HDN reaction of cyclohexylamine only provides benzene and methane, with no apparent formation of cyclohexane. Thus dehydrogenation is an important side reaction.
