摘要

摘要: 利用傅里叶变换红外光谱仪分析了脱水的霍林郭勒褐煤(HL)及其超临界乙醇解所得萃取物和萃余物,并利用气相色谱/质谱联用仪分析了萃取物。根据分析结果考察了HL超临界乙醇解的机理,发现HL超临界乙醇解过程中存在烷基取代和醚氧桥键的断裂反应,且以脂肪族醚氧桥键的断裂为主。

Abstract: The dehydrated Huolinguole lignite (HL) together with the extracts and the extraction residues obtained from supercritical ethanolysis of HL were analyzed by Fourier transform infrared spectrometry (FT-IR). The extracts were further analyzed by gas chromatography/mass spectrometry. The mechanism for supercritical ethanolysis of HL was discussed according to the analytical results. The supercritical ethanolysis of HL includes alkyl substitution and cleavage of ether bonds. The cleavage of ether bonds is mainly occurring in aliphatic ether bonds.
