Abstract

Disclosed are methods to obtain useful lignin fractions by fractionation of technical lignins. In some methods, successively solvents of increasing polarity are applied and/or an extraction column is used which provided with a packed stationary phase comprising technical lignin mixed with inert particles having a particle size in the range of from 1 to1000 micrometers. Disclosed is also an extraction column provided with a packed stationary phase, wherein the packed stationary phase comprises technical lignin mixed with inert particles having a particle size in the range of from to 000 micrometers.
