Carbon-13 nuclear magnetic resonance spectra of model hydroaromatic hydrocarbons and solvents
Carbon-13 NMR chemical shifts were assigned for the various types of carbon atoms in tetralin, alkyletralins, 9,10-dihydrophenanthrene, sym-octahydrophenanthrene,1,2,3,4-tetrahydrophenanthrene, 4,5-dimethyl-9,10-dihydrophenanthrene; 4-n-decyl-1,2,3,6,7,8-hexahydropyrene; 4,5,9,10-tetrahydropyrene, and 1,2,3,9,10,11-hexahydropyrene, which are all model compounds for the hydrogen donor solvents used in coal liquefaction and the factors affecting the chemical shifts were analyzed. The results were used to identify the hydrogenation products of phenanthrene and pyrene; in both cases, complex mixtures of the above species as well as unconverted parent aromatics and ring-opened cracking products were observed. 17 references
