| titleOfInvention | Method for extracting lignin by using ternary deep eutectic solvent |
| abstract | The invention discloses a method for extracting lignin by using a ternary deep eutectic solvent. The method comprises the following steps: mixing the raw materials with a ternary deep eutectic solvent for reaction, cooling to room temperature after the reaction is finished to obtain a reaction product, adding the reaction product into absolute ethyl alcohol, stirring, washing with the ethyl alcohol, filtering, concentrating, adding water, standing to obtain a precipitate containing lignin, filtering, and drying to obtain the lignin. Compared with a binary deep eutectic solvent, the method for extracting lignin from straws by using the ternary deep eutectic solvent provided by the invention has the advantages that the extraction efficiency of lignin is more effectively improved, the maximum extraction efficiency within 4 hours is 84 +/-1%, the purity of the obtained lignin is higher, the maximum purity is 83%, the deep eutectic solvent and absolute ethyl alcohol can be recycled in the extraction process, compared with the traditional organic and inorganic acid-base treatment, the problems of pretreatment cost, environmental pollution and the like are reduced, and the method conforms to the green environmental protection development concept. |
