A kind of carboxylated lignin derivative and preparation method thereof |
| abstract |
The present application relates to a carboxylated lignin derivative and a preparation method thereof. The carboxylated lignin derivative is characterized in that, in the structure of the carboxylated lignin derivative, the carboxyl groups on the lignin formed by opening 1-15% of the benzene ring through an oxidation reaction and non-ionic Type hydrophilic group grafting. The carboxylation method of the present application does not sacrifice a large number of phenolic hydroxyl groups in lignin, generates new carboxyl groups through ring-opening of the benzene ring, and significantly improves the activity of lignin. |
