| Abstract: | A heterogeneous catalytic system for methylolation of alkali lignin was constituted of tetrahydrofuran containing purified alkali lignin and solid alkali catalyst with special structure . In order to investigate the efficiency of the catalyst for various raw materials,two types of alkali lignin were used as material,physical properties of the methylolated lignins which were produced through homogeneous phase catalysis methylolation and heterogeneous phase catalysis methylolation were compared. |
