High boiling fraction (265-316°C, 0.3 mmHg) of benzene extract of Yubari coal was fractionated by column chromatography and the saturated part was separated to urea adduct and to non adduct. The former is the n-paraffine mixture which contains C15 to C70, having a maximum at C35-C40. The latter is supposed to be mainly a mixture of isoprenoids of which the mean supposed structure is
CH3-(CH3-CH-CH2-CH2-CH2-) 5-CH3
The following fraction which has UV absorption of naphthalene nucleus, was examined by IR, UV, NMR and mass spectrum. The results of structural analysis of that fraction and of a supposed mean structure
coinside very well.
From the another lowest boiling fraction (-100°C, 4 mmHg) of benzene extract, adamantane was separated and confirmed. The amount of adamantane in the original coal is 0.16ppm.
