| Abstract: | The delignification of wheat straw with alkali-oxygen cooking was studied, and the effects of technological conditions on delignification of wheat straw were discussed. The results showed that appropriate conditions of delignification were temperature 160C, concentration of NaOH 8%, pressure of oxygen 0.8 MPa, the ratio of solid(wheat straw) to liquid 0.14 and time of heat preservation l h. At the same time, the structure of lignin was annalyzed by means of IR and 1H-NMR. |
