| Abstract: | The lignin was extracted from straw with extractant of 1 ,4-butanediol solution by microwave radiation. Studies were conducted on the effects of microwave radiation power, microwave radiation time,solid-liquid ratio and mass fraction of extractant on the extraction yield of lignin. The optimal extraction conditions are as follows; microwave radiation power; 900 W, microwave radiation time; 40 min, solid-liquid ratio:1/12(g ·mL~(-1)) , mass fraction of extractant: 90% . The extraction yield under such conditions was 45. 5% . |
