Abstract
Soluble modifications of lignin were obtained by means of alkaline and oxidative processing of nitro lignin. Using mono- and triethanolamine as alkaline reagents, we obtained lignin compounds of the type of quaternary ammonium salts. Complex compounds of zinc (II), iron (III), nickel (II) and copper (II) with nitroligninmono- and triethanolammonium were synthesized. The composition, structure and thermal stability of the new modifications of nitrolignin and its metal complexes were established with the help of IR spectroscopy, X-ray diffraction, chemical analysis and derivatography.
