For the selective extraction of low MW lignin with various solvents (dichloromethane, acetone and methanol), it was found that among all samples, there were no significant differences in MW, except for the sample extracted from dichloromethane. The starting lignin precipitated from black liquor at pH 4 and lignin extracted with acetone and methanol possessed similar MW values ranging from 1,363 to 1,474 g mol-1, whereas lignin extracted from dichloromethane possessed lower Mw (942 g mol-1). Lignin with a high fraction of lower MW molecules is more suitable for condensates with phenol formaldehyde, because it is more reactive than with high MW molecules (Pizzi, 1994). Thereby, it seemed to be possible to use the dichlormethane- soluble lignin in the formulation of a lignin-based resin/adhesive.
