Abstract

The relationship between the cross-cut distribution of bitumen (raw crude mountain wax) and the nature of the organic matter of coal from the Sergeevskoe brown coal deposit was investigated. It was found that bitumen of terrestrial genesis was present in a maximum concentration (15%), whereas bitumen of aquagenic origin had a minimum concentration (4%). Humic acids (70%) were evenly distributed throughout the deposit. Four groups of compounds were identified in the composition of waxes, the main of which was an aliphatic ether fraction (about 60%). The individual composition of waxes, resins, and humic acids was studied by IR and NMR spectroscopy, gas chromatography, and gas chromatography–mass spectrometry. The extraction of not readily available mountain wax and humic substances was recommended as the most promising direction of using the chemical potential of the Sergeevskoe brown coal deposit.

来自 Sergeevskoe 矿床（阿穆尔州）的煤潜在化学转化产物的组成和横向分布

摘要

研究了沥青（原始粗山蜡）的横切分布与来自 Sergeevskoe 褐煤矿床的煤的有机质性质之间的关系。发现陆生沥青的浓度最高 (15%)，而水生沥青的浓度最低 (4%)。腐殖酸 (70%) 均匀分布在整个沉积物中。在蜡的组成中确定了四组化合物，其中主要是脂肪醚部分（约 60%）。通过红外光谱和核磁共振光谱、气相色谱和气相色谱-质谱法研究了蜡、树脂和腐殖酸的各个组成。
