摘　　要：在相同的实验条件下,对四种不同煤阶的煤用搅拌抽提法进行吡啶抽提,并利用傅立叶变换红外光谱(FTIR)对原煤及残煤进行了定量测试,讨论了不同抽提率产生的原因,研究了吡啶抽提前后官能团含量的变化。分析表明,溶剂吡啶主要作用于煤基本结构单元芳核的侧链和桥键。Using pyridine stirring extraction, four different ranks of coals were extracted in the same experiment conditions. Organic function groups of coal samples and residues were tested using Fourie transform infrared spectroscopy (FTIR). The cause of different extraction yield was discussed and the change in amount of organic function groups of coal before and after extraction was analyzed. The results show that pyridine mainly acts with the side chains and bridge of basic unit in coals.
