摘要:
The invention relates to a method of isolating a lignin fraction from a solution comprising solubilised lignin, the method comprising the steps of adding water to a solution comprising solubilised lignin and a hydrotrope, thereby lowering the hydrotrope concentration, until a part of the lignin becomes insoluble, and isolating the insoluble lignin.
