College of Material Science and Engineering,Northeast Forestry University, Harbin 150040, China; 2.Institute of Che ical Industry of Forest Products, CAF,Nanj ing 210042, China) Abstract: Cationic flocculant of quaternary ammonium salt of lignin was synthesized using sulphate lignin from papermaking black liquor .The decolourizing performance of quaternary ammonium salt of lignin and effects of different catalysts on the synthesiswere studied. Quaternary ammonium salt of lignin was investigated through infrared spectrum( FTIR) . Flocculation performance of the salt applied to dye liquor of high concentration and high colority has been quantitatively analysed. Results indicate that cationic flocculant of quaternary ammonium salt of lignin can be synthesized by grafting reaction. ynthesis of monomeric quaternary ammonium salt was carried out at: mole ratio of tr-i methylamine and chloro-cyclopropane 10. 7, tem- perature from - 3 to - 6 .Ammonium
