Abstract

Abstract: Pyridine -insoluble、THF-insoluble solids of bydrocrachng products of vitrain pyridine-insoluble solid and itself were investigated by solid state ¹³C CP/MAS NMR technique.From the measurements, twelve structural parameters of carbon skeleton were obtained Benzene-soluble subfraction of hydrocracking products were investigated by one and two dimensions ¹H and ¹³C liquid NMR techniques.Their ¹H and ¹³C spectra were assigned.The avcrage molecular structures of these fractionswere obtained.

Key words: Vitrain, Pridine-insoluble, Hydrocracking, NMR, Average molecular structure
