| 摘 要： | 用超声波和微波辐射法在四氯乙烯体系下，采用气相色谱／质谱仪对北京煤、王庄煤、兖州煤和临汾煤进行了萃取液分析．结果表明，不同煤样在超声波作用下的脱硫效果不同，不同煤样四氯乙烯萃取物中分别含有苯并噻唑、苯并噻吩、噻克索酮、2-甲基-4-叔丁基苯硫酚、噻唑基嘧啶、甲苯噻嗪、5-乙氨基-噻唑基嘧啶、4-氨基-噻嗪、4-甲氧基-2-甲基-1-甲硫醚基苯、2-甲硫基-苯并噻唑和2-甲硫基-苯甲酸甲酯等硫化物。 |

| Abstract: | In this paper desulphurization Linfen were investigated by tetrachloethylene of coals from Beijing,Wangzhang,Yanzhou and extraction under ultrasonic and microwave irradiation. Tetrachloethylene extraction liquid was analysed by GC-MS. The results of experiments show that desulphurization effect of different coals are unlikeness under ultrasonic. Tetrachloethylene extractions of different coals contain benzothiazole,benzothiophene,tioxolone, 2-methyl-4-tert-butyl-benzenethiol, thiazolyl-pyridine, xylazine, 5-ethylamino-thiazolyl-pyridine, 4-amido-thiazolyl, 4-methoxy-2-methyl-1-methylthio-benzene, 2-methylthio-benzothiazole and 2- methylthio-methyl benzoate. |
