Overview

A systematic analysis investigates diol-based DES pretreatment effects on lignin extraction from Pinus massoniana, highlighting significant improvements in yield.

Key Points

  • The aim is to evaluate the effects of diol-based deep eutectic solvents (DES) on lignin extraction from Pinus massoniana.
  • Developed a diol-based DES system using Choline chloride, AlCl3, and BDO.
  • Conducted pretreatment at 130 °C to assess glucan and xylan recovery yields.
  • Analyzed lignin structure and retention using FT-IR and 2D-HSQC techniques.
  • Achieved glucan recovery yield of 92.95% and xylan yield of 71.73% at 130 °C.
  • Lignin removal yield reached 61.96% with preservation of β-O-4' linkage content at approximately 51.63%.
  • Total phenolic -OH content significantly increased after pretreatment.
