Abstract

A plausible chemical structural unit for Akabira bituminous coal is proposed. The strategy employed here was: (1) SRC (94% yield) from Akabira coal was chosen for study; (2) Possible conversion of coal constituents during SRC processing due to heating was evaluated by comparing the constituents of the SRC pyrolysate with those from extracts obtained at ambient temperature; (3) Curie point pyrolysis gave the means to estimate the constituents contained in the SRC fractions; (4) Distribution of the aromatic compounds was obtained from the pyrolysis data; (5) Distribution of aliphatic carbons was based on CP/MAS ¹³C-NMR data of original coal. A unit structure of C₃₈₃H₃₇₂O₃₈N₆ (molecular weight 5667.237) is proposed.
