“…However, because acid also catalyzes the fragmentation of lignin macromolecules, and the lignin fragments are further solubilized by solvents. Therefore, CSF also has been applied to evaluate and optimize acid‐catalyzed ethanol pre‐treatment of biomass . However, for different biomass, the optimal CSF is varied, but typically the CSF selected is in the range of 1.0–2.5 to obtain good cellulose recovery and enzymatic digestibility depending on the biomass feedstocks.…”

Over the years, the organosolv pulping process has proven to be a valuable pretreatment method for various lignocellulosic feedstocks. The objective of this study was to characterize and assess the potential applicability of the organosolv lignin fraction from European larch sawdust, as no research has been conducted in this field so far. Eight different samples were prepared from the European larch sawdust under varied reaction conditions and one milled wood lignin sample as reference. The reaction temperature and sulfuric acid loading were varied between 420 and 460 K and 0.00 and 1.10% (w/w on dry wood basis) H2SO4, respectively. The antiradical potential (via DPPH• method), chemical structure (via ATR-FTIR, 1H NMR, 31P NMR, and thioacidolysis), as well as the molecular weight distribution of the isolated lignins were analyzed and compared. Results from thioacidolysis show a direct correlation between the amount of β-ether bonds broken and pulping process severity. Similarly, both antiradical potential and phenolic hydroxyl group content exhibit a direct relationship to reaction temperature and catalyst loading. On the contrary, the content of aliphatic hydroxyl groups and the average molecular weights both decreased with increasing process severity. The high content of phenolic hydroxyl groups and antioxidative potential of the larch organosolv fractions, especially for the sample isolated at 460 K and 1.10% H2SO4 loading, indicate good applicability as antioxidants as well as feedstocks for further downstream valorization and require additional research in this area.

“…Generally, CSF is a parameter that has been used mainly in liquid hot water pretreatment and autohydrolysis (steam explosion) (Montané, Farriol, Salvadó, Jollez, & Chornet, 1998). Nowadays, CSF is also applied to evaluate and optimize acid-catalyzed ethanol organosolv pretreatment (Chum, Johnson, & Black, 1990;Gandolfi, Ottolina, Consonni, Riva, & Patel, 2014;Jang et al, 2016). The optimal CSF varies with the types of biomass, and, typically, the CSF selected is from 1.0 to 2.5 to get good cellulose recovery and improve the enzymatic digestibility.…”

Lignocellulosic biomass is one of the potential feedstocks to produce second-generation cellulosic ethanol and biochemicals. To enhance the enzymatic digestibility of lignocellulosic biomass for efficient enzymatic saccharification, a variety of pretreatment methods have been studied. Among these, organosolv pretreatment using ethanol is a promising pretreatment method owing to its inherent advantages, such as low solvent cost, lack of toxicity, the ability to retain most cellulose fraction in substrates for enzymatic hydrolysis, coproduction of high-purity lignin and hemicellulosic sugars, easy solvent recovery, and reuse. In this review, the research progress regarding different types of ethanol organosolv pretreatment processes has been summarized in terms of methods, substrate properties, reaction mechanisms, delignification kinetic as well as the impact of pretreatment methods on the enzymatic digestibility. Attempts are also made to provide insights into the complete utilization of lignocellulosic biomass to achieve high potential revenues. Though some ethanol organosolv processes have been studied or are being developed towards commercialization, ethanol organosolv pretreatment is still facing some challenges. Finally, the direction for future work is given to develop a proper ethanol organosolv pretreatment for commercialization.
