| Abstract: | Kovac-Peppas method was used to measured the change of coal before and after solvent extraction,The decreased of cross-link density was observed by both pyridine and cyclohexanone extraction of raw coal.However the cross-link density of alkali pretreated coal changed in different ways,which increase after pyridine extraction but decrease after cyclohexanone extraction. |

| Keywords: | coal cross-link swelling solvent extraction solubility parameter |
