| Abstract: | The contents of cellulose, hemicelluloses and lignin were first analyzed and compared in three agro-industrial residues; and then a new method was developed to extract hemicelluloses with ionic liquid. The study investigated the effect of the extraction conditions and optimized them by Box-Behnken experiment design. When the ionic liquid concentration was 30.08 %, temperature was 90.31 °C, reaction time was 4.10 h and the ratio of liquid/solid was 25.97, the yield of hemicelluloses could reach 52.02 %. The green extraction solvent could be efficiently recycled for five times. Moreover, the chemical structure and thermal stability of obtained hemicelluloses were characterized. |
