核磁共振法应用于煤液化油中酚类化合物分析

NMR methods used to analysis the phenolic compounds in coal-derived liquid

介绍了多种核磁共振方法应用于分析煤炭直接液化产物中酚羟基含量及酚类化合物组成等方面的情况,逐一评析了每种方法的优劣。

Phenolic compound, the predominant oxygen-contained compound in coal-derived liquid, would be the potential high-profitable byproduct of direct coal liquefaction process. The fundamental step for using the product, however, to differentiate and quantitate these compounds accurately, is still an enormous task so far, since these compounds have high boiling point and strong polarity generally. In this manuscript, almost all kinds of NMR methods used to analysis the phenolic compounds in coal-derived liquid were summarized comprehensively. The advantages and disadvantages of each NMR method were also comment on.
