Recovering ultraclean lignins of controlled molecular weight from Kraft black-liquor lignins

Author affiliations

Abstract

By operating in a region of liquid–liquid equilibrium, hot acetic acid–water mixtures can be used to simultaneously clean, fractionate, and solvate Kraft black-liquor lignins. Lignin-rich liquid phases of controlled molecular weight with key metals contents reduced to <50 ppm are obtained without a washing step.
