| titleOfInvention | A method for rapid and high-yield separation of lignin with green solvent |
| abstract | The present invention provides a method for separating lignin with green solvent in rapid and high yield, comprising the following steps: (1) mixing and heating the first hydrogen bond donor, the second hydrogen bond donor and the hydrogen bond acceptor to obtain a homogeneous phase Transparent ternary deep eutectic solvent; (2) adding lignocellulose raw material to the ternary deep eutectic solvent described in step (1) for heat treatment to obtain slurry; (3) adding lignocellulosic raw material to the slurry obtained in step (2) Add acetone aqueous solution and stir, then filter to obtain filtrate, then use acetone aqueous solution to wash the filter residue until the washing solution is colorless, and combine the filtrate and washing solution; (4) carry out evaporation and concentration, then extract, add saturated brine for regeneration, and finally obtain lignin . The process of the invention is easy to operate, low in cost and environmentally friendly. |
