Abstract

The influence of ultrasonication on the O-alkylation of the organic matter of brown coal from the Tyul’ganskoe deposit of the South Ural basin was investigated. The positive influence of this treatment method on the yield of bitumoids was shown. Data on the group and component compositions of bitumoids extracted from brown coal O-alkylated under the influence of ultrasound were presented. A number of biologically active substances, including octacosanoic acid, hexacosanoic acid, oleic acid, ferruginol, and n‑tetracosanol-1, were identified in the composition of the test bitumoids using gas chromatography–mass spectrometry analysis.

超声波作为一种提高褐煤 O-烷基化中沥青产量的方法

摘要

研究了超声波处理对南乌拉尔盆地 Tyul'ganskoe 矿床褐煤有机质 O-烷基化的影响。显示了这种处理方法对沥青产量的积极影响。介绍了在超声波影响下从 O-烷基化褐煤中提取的沥青的组和组分组成数据。使用气相色谱-质谱分析在测试沥青的组成中鉴定了许多生物活性物质，包括二十二烷酸、六十二烷酸、油酸、铁锈醇和正二十烷醇-1。
