Fractionation of guaiacyl and syringyl- lignin units using organic solvent nanofiltration

Key Points

• Distinct fractions of guaiacyl and syringyl lignin units were effectively separated through organic solvent nanofiltration.
• The study highlights that specific organic solvents enhance the fractionation process between lignin units.
• Analysis was conducted using nanofiltration techniques across various organic solvent types, refining the lignin extraction process.
• This approach supports future applications in lignin-based biofuels, enhancing material recovery and usage.
