采用氯仿对煤样平顶山八矿原生结构煤和构造煤对比样品进行充分萃取,由实验结果可知,两者氯仿萃取率差别较大,构造煤比原生结构煤高一倍多.由此看来,与原生结构煤相比,构造煤萃取物的组成饱和烃含量稍低,而极性芳烃化合物含量高一些.构造煤在力化学作用下,具有更强的脱侧链能力,从芳核上脱落的侧链可能运移出其母体,也可能吸附在其母体上.因此其低分子化合物的含量较高.
构造煤形成过程中,正构烷烃类化合物变化显著,构造煤由于受到构造应力作用下发生破碎甚至强烈的韧塑性变形,造成煤中碳链断裂,并形成轻质组分在煤层中运移或排出,造成构造煤中重质组分明显增多.构造煤形成过程中,由于芳构化作用,稠合芳烃系列化合物含量增加,但又伴随裂解作用.化学稳定性差的非稠环芳烃、混环芳烃化合物含量减小.

Using chloroform on coal Pingdingshan primary coal and construction of coal samples were compared to fully extract from the experimental results,large differences between the two chloroform extraction,construction of coal higher than the original structure of coal more than doubled.Seen in this light,compared with the original structure of coal,coal structure the composition of extracts was slightly lower content of saturated hydrocarbons,while the higher content of polar aromatic compounds.The chemical structure of coal under the action of the force,with more capacity off the side chain,from the aromatic side chain may be falling on the migration out of its parent,may also be absorbed on the matrix.So its high content of low molecular weight compounds.
Structure during the formation of coal,alkanes compounds changed significantly,due to tectonic structure of coal were fractured under stress or even a strong tough plastic deformation,causing the carbon in coal strand breaks and formation of light fractions in coal bed or discharge,resulting in construction of coal in the heavy components significantly increased.Construction of coal formation process,because of the role of aromatization,fused aromatic compounds were increased,but with decomposition.Poor chemical stability,non-condensed aromatic,mixed aromatic compounds content decreases.
