Modified lignin with ion-exchange properties
- 73 Downloads
Polyfunctional ion-exchangers were synthesized by heterophase amination of α-oxide derivatives of hydrolyzed lignin with aliphatic di-and polyamines. Optimal conditions for their preparation were determined. Certain physicochemical properties were studied.
