Abstract:: ... Lignin’s heterogeneous polymeric structure limits its utilisation in high-value applications. This paper describes a protocol for kraft lignin precipitation fractionation from aqueous ethanol, acetone and propyleneglycol monomethyl ether solution by adding water as nonsolvent. The solvent-insoluble fractions possessed high molar mass (Mw 4300–18900g/mol), high polydispersity (2.2–5.6), high nitrog ...
