【摘要】 利用气相色谱 质谱联用 (GC MS)技术测定了平朔、大同和神府三种烟煤中CS2 萃取物的成分 ,对其化学组成及结构特征进行了对比研究。结果表明 ,萃取物主要由脂肪烃、芳烃和含杂原子化合物三类成分组成。芳烃在萃取物整体中占绝对优势 ,以苯系、萘系、菲系和芘系的烷基取代芳烃为主要成分 ;脂肪烃除主要成份正构烷烃外 ,还有少量的类异戊二烯烃和萜烷 ;含杂原子化合物所占的比例很小 ,以含氧、氮和硫的化合物为主 ,在平朔和大同煤的CS2 萃取物还发现少量邻二氯苯。更多还原

【Abstract】 The CS 2 soluble fractions from Pingshuo, Datong and Shenfu bituminous coals were analyzed using GC/MS and their chemical constituents and structural characteristic were studied. The results show that the CS 2 extracts mainly consist of arenes, aliphatic hydrocarbons and heteroatom-containing compounds. Arenes are dominant components among which benzene, naphthalene, phenanthrene and pyrene ring-contaning compounds with and without alkyl substitutes are main components. Aliphatic hydrocarbons primarily consist of n-alkanes with small amounts of acyclic isoprenoids and terpanes. Only very small amounts of heteroatom-containing compounds were detected, among those oxygen-, nitrogen- and sulfur-containing compounds are main components. Small amounts of o-dichlorobenzene were found in the CS 2 soluble fraction from Pingshuo and Datong coals.更多还原
