LMPs isolation yields and characterization for beech, spruce, wheat straw, and kraft lignin. Mw represents the average molecular weight.
| LMPs Characterizations | Organosolv 200 °C 60 min 60/40 EtOH/H2O (v/v) | Kraft | ||
|---|---|---|---|---|
| Beech | Spruce | Wheat Straw | ||
| Extraction yields (wt%) | 69.7 ± 0.8 | 35.9 ± 1.2 | 44.8 ± 0.4 | / |
| Purity (%) | 93.0 ± 0.4 | 96.1 ± 0.1 | 96.3 ± 0.7 | 91.5 ± 0.3 |
| Sulfur content (%) | ˂0.05 | ˂0.05 | ˂0.05 | 1.8 |
| Mw (kDa) | 20.8 | 15.7 | 17.2 | 29.4 |
LMPs extraction (wt%) yields are based on raw lignin biomass content. Results include lignin purity (%), sulfur content (%), and average Mw from SEC.
