FIELD: organic technology. SUBSTANCE: organic halogen derivatives having common formula XMR1R2 where if X=Cl, Br, then M is CH; R1 is H, X, alkyl, alkoxy, C6H5; R2 is R1;CH=CH2; CH=CHX; CH=CXCH3; CH=CHCH2X; CHXCH2; CH2X; CHOHCH2X; CH2OCH2CH2X; CH2N(CCH2CH2X)2; CH2SCH2CH2X; COOY; COR1; if X is F,Cl,Br, then M is ; R1 is X; C1 - C6 alkyl, C1 - C6 alkoxy; R2 is R1; C(C6H5)=CHX; CH=CHX or mixture thereof or medium comprising them are neutralized by contact with aqueous-alkali solutions of lignin-containing wastes. EFFECT: improved efficiency. 3 tbl |
