运用G C-M S法对云南石屏泥炭树脂的化学成分进行了分析研究。结果表明,其中芳香类化学成分较少,含不饱和键的环状或链状结构的化合物居多。与已有研究报道的褐煤树脂的化学成分相比,云南石屏泥炭树脂化学成分的环化程度、聚合程度、分子量都相对较低。以上结果说明云南石屏泥炭是一种比褐煤煤化程度更低的成煤初始沉积物。
The chemical composition of peat resin from Shijing in Yunnan Province was analyzed by G C-M S method. The results showed that most of the compounds with aromatic or less aromatic ring or chain structure containing unsaturated bonds were found. Compared with the chemical composition of lignite resin reported in previous studies, the degree of cyclization, the degree of polymerization and the molecular weight of the chemical components of the peat resin in Shifin, Yunnan Province are all relatively low. The above results show that the Shifin peat in Yunnan Province is a coal formation initial coal deposit with lower degree of coalification than lignite.
