摘要
采用酸碱分离和萃取色谱分离方法将陕西神木地区低温煤焦油分离为酸性组分、碱性组分和5个中性组分。采用气相色谱-质谱(GC-MS)和负离子电喷雾傅里叶变换离子回旋共振质谱(ESI FT-ICR MS)鉴定了神木低温煤焦油酸性组分、中性组分4和中性组分5中含氧化合物的组成与分布。结果表明,神木低温煤焦油酸性组分中含氧化合物主要包括苯酚、茚满酚、萘酚、联苯酚、芴酚、菲酚类化合物;中性组分4和中性组分5中含氧化合物主要包括C10～C29脂肪酮和少量芳香酮。神木低温煤焦油中含氧化合物主要有O1、O2、O3、O4、O5、O6类化合物,其中O2类化合物相对丰度最高。
The methods of acid-base separation and extrography were used to separate Shenmu low temperature coal tar into acid fractions, base fractions and five neutral fractions. The molecular structure and mass distribution of oxygen containing compounds in Shenmu low temperature coal tar were investigated by using gas chromatography-mass spectrometry （GC-MS） and negative-ion eleetrospray ionization Fourier transform ion cyclotron resonance mass spectrometry （ESI FT-ICR MS）. The results showed that the oxygen containing compounds in acid fractions involved phenols, indanols, naphthols, phenylphenols, fluorenols, phenanthrenols. The oxygen compounds in neutral fraction 4 and 5 involved aliphatic ketones ranging from C10 to C29 and minor aromatic ketones. The class species of O1, O2, O3, O4, O5, O6 were found in Shenmu low temperature coal tar, among which the O2class species had the highest relative abundance.
