用高锰酸钾碱性溶液对黄县褐煤进行了九步氧化,按先后次序将产物分为两个馏份进行分析鉴定。有机酸碳收率达76.5％。对两个馏份酸用乙醚抽提并经甲酯化后分别进行了色-质谱分析,鉴定出六十多种单体化合物,主要有脂肪二元酸及一元酸、芳香二元酸及一元酸,多官能团酸,此外还有一些非酸化合物,如酮、醇、胺、含氮和硫的杂环化合物以及烃类等。配合元素分析及红外光谱分析等对产物进行了较为全面的分析鉴定。
Huangshan brown coal was subjected to nine-step oxidation with potassium permanganate alkaline solution, and the product was divided into two fractions for analysis and identification in order of priority. Organic acid carbon yield of 76.5%. The two fractions of acid were extracted with ether and subjected to colorimetric-mass spectrometry after methyl esterification. Sixty monomer compounds were identified, mainly fatty dibasic acids and monobasic acids, aromatic dibasic acids and monobasic Acids, polyfunctional acids, in addition to some non-acid compounds such as ketones, alcohols, amines, nitrogen and sulfur containing heterocyclic compounds and hydrocarbons. With the elemental analysis and infrared spectroscopy analysis of the product a more comprehensive analysis identified.
