山西肥煤正己烷萃取物的FT-IR分析

he fat coal collected from Shanxi Xingzhi was extracted with the solvent of n-hexane and sampled based on a given period of time, Then the extracts were analyzed with FTIR. The infrared spectrum was divided to four parts which were analyzed separately by the procedure of curve resolution from PeakFit V4.12. The contents and the dissolving fenture of functional groups were acquired according to the datas of curve resolution. The results show that there are five types of hydroxyl in the extracts, and the contents of hydrogen bonds were followed by OH-ether ＞ self-association ＞OH-π ＞ hydroxyl ring ＞ free hydroxyl.To the aliphatic hydrocarbon, long carbochain was more difficult than the short ones when it comes the dissolving ability. what’s more,there were lots of substitutional groups which contained ortho substituted two and ortho substituted three mainly and less ortho substituted five in the aromatic hydrocarbon compounds.
