In order to investigate the compositions of soluble organic compounds in low-rank coals, Xinjiang Changyan coal (XCC) was selected in this subject. On this basis, XCC was made to undergo ultrasonic extraction (UE) in a mixed solvent toluene/ethanol with synergistic effect and the soluble mixture was...
