摘　　要：A high-temperature coal tar （HTCT） was sequentially extracted with petroleum ether （PE）, ethyl acetate （EA）, and acetone with ultrasonic irradiation to afford extracts 1 to 3 （El to E3）, respectively, and acetone residue. The gas chromatography/mass spectrometry （GC/MS） analysis of all extracts show that E1 is mainly composed of diand tricyclic arenes such as naphthalenes, phenan- threne, anthracene, etc., whereas high contents of heteroatomic compounds and four or more ring arenes were found in E2 and E3, respectively. The pyrolysis process of acetone residue was studied with a thermogravimetric （TG） analyzer equipped with Fourier transform infrared （FTIR） spectrometer. The results indicate that volatiles were mainly released at 380-560 ℃, and the maximum mass loss rate occurred at 492 ℃.A high-temperature coal tar （HTCT） was sequentially extracted with petroleum ether （PE）, ethyl acetate （EA）, and acetone with ultrasonic irradiation to afford extracts 1 to 3 （El to E3）, respectively, and acetone residue.
