【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.更多还原

【Abstract】 In this paper desulphurization of coals from Beijing,Wangzhang,Yanzhou and Linfen were investigated by tetrachloethylene 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.更多还原
