The amine unit is grafted in lignin through Manrich reaction to compound a kind of cationic surfactant-lignin amine.The nitrotrogenous content and the modification rate of the modified lignin is measured by elementary analysis. and acetate - cellulose film electrophoresis. The main factors which affect the nitrogenous content and the modification rate and the best technological conditions are determined by adopting three factors one power-regression orthgonal design.
