煤中氧的存在形式和含氧量是研究煤物理结构和化学性能的基础。本文对煤中含氧官能团的各类分析方法进行了总结,介绍了确定煤中羟基(醇羟基和酚羟基)、羧基、羰基、醚键等含氧官能团的化学及物理定性与定量方法。并对这些方法的易操作性、准确性等进行了比较,旨在从分析测试机理和煤结构组成出发,了解煤中含氧官能团和相关煤结构的分析进展。
The content and existing forms of oxygen in coal have a decisive effect on the qualities, acid characteristics of coals and pyrolytic reaction. Analysis of oxygen-containlng functional groups in coal is the fundamental method for understanding coal physical structures and chemical properties. The analysis methods of oxygen-containing functional groups, such as hydroxyl groups ( alcohol hydroxyl and phenolic hydroxyl), carboxyl, carbonyl, and ether bond in coal and their chemical and physical methods of qualitative and quantitative determinations were introduced. The maneuverability and accuracy of these methods had been discussed.
