Abstract

Fractional extraction of Beisu coal with ethanol and ethyl acetate was carried out to study the existence form and dissolution behavior of the organic matter in Beisu coat. Fourier transform infrared (FTIR) is used for the analysis of various abstract. The results show that the dissolution of organic matter in ethanol and ethyl acetate is a gradual precipitation process. With the increase of the extraction number, the extraction quality of each extract increased first and then decreased, and the extraction rate of these two extracts was the highest in the 3rd time. The quality of the ethanol extract was significantly higher than that of the ethyl acetate extract. These two solvent extraction have good effect on the matter containing -OH, aliphatic side chain structure, aromatic structure. The structure of -OH, benzene ring and -C-O is rich in the Beisu coal, but the C=O functional groups are less. The study has important basic theoretical significance in the development of high value-added utilization of coal.
