Abstract evidence

A new organosolv pretreatment medium (OPM), 1-pentanol (80%, v/v)-water mixture [dH = 27.4 (J/cm3)^(-1/2)], was discovered based on Hildebrand solubility parameter (dH) theory. This OPM enabled the near-complete removal of non-cellulosic components (hemicellulose 96.2%, lignin 87.8%) from bamboo under mild conditions [130 °C, 20 min, 4% (w/w) H2SO4].

Mechanism / Method Highlights

  • Hildebrand solubility-parameter matching promotes lignin dissolution: the closer the dH values of solute and solvent, the higher the solubility. The hydroxyl group of 1-pentanol forms hydrogen bonds with lignin hydroxyl groups, disrupting the intermolecular hydrogen-bond network and promoting lignin extraction.
  • Rapid and uniform microwave heating accelerates pretreatment by coupling directly with polar water/alcohol molecules and disrupting lignocellulosic structure.
  • Removal of hemicellulose and lignin exposes cellulose microfibrils and increases specific surface area by 9.7-fold.
  • Soy protein can preferentially adsorb on residual lignin, protecting cellulase from nonproductive adsorption and improving enzymatic conversion.

Application Value

  • Uses Hildebrand solubility-parameter theory to screen the organosolv pretreatment medium.
  • Achieves 96.2% hemicellulose removal and 87.8% lignin removal, approaching near-complete non-cellulosic component removal.
  • At low enzyme loading, cellulose enzymatic conversion reaches 92.6%, far above the below 63% level of other OPM conditions.
  • Preserves quantitative result evidence: Specific surface area 9.7-fold, Hemicellulose (xylan) removal 96.2%, Cellulose enzymatic conversion 92.6%, and Hemicellulose removal 96.2%.
  • Maintains source-level evidence details: Energy-comparison evidence: source values include 130 °C, 20 min, 96.2%, 87.8%, 92.6%, Energy-comparison evidence: source values include 130 °C, 20 min, Abstract evidence: A new organosolv pretreatment medium (OPM), 1-pentanol (80%, v/v)-water mixture [dH = 27.4 (J/cm3)^(-1/2)], was discovered based on Hildebrand solubility parameter (dH) theory.
