Alkaline soda lignin (AL) was sequentially fractionated into six fractions of different molecular size by means of solvent extraction and their phenolic hydroxyl groups were chemoselectively methylated to determine th...
Hydroxyl groups are abundant in the lignin structure and they have different types randomly allocated, with several levels of reactivity towards diisocyanate. The main hydroxyl groups in lignin are aliphatic (R–OH) an...
The fine structural changes of phenolic hydroxyl groups of cinnamic acid and its derivatives affects their inhibition mechanism and interaction with α-glucosidase
The quantification of lignin functional groups constitutes an essential step for effective assessment of lignin transformation. A new, fast, economical, and simple method without the use of harmful solvents is present...
The phenolic hydroxyl group is one of the most important functionalities affecting the physical and chemical properties of lignin polymers (Adler 1977). It plays a prominent role in commercial pulping and bleaching pr...
Furthermore, the reactivity difference between aliphatic and phenolic hydroxyl groups when treated with aromatic isocyanates is also seen in LHO. Indeed, the aliphatic hydroxyl groups cure faster than the aromatic hyd...
The polar and weakly acidic carboxylic (COOH) and phenolic hydroxyl (ArOH) functional groups play major roles in the acid nature, pH dependent solubilities, conformation, and metal- and salt-binding capabilities of HS.
In this paper, the initial stage of the pyrolysis process of phenolic resin has been simulated by ReaxFF (reactive force field) molecular dynamics simulation under various temperatures (3000 K, 3250 K, and 3500 K), to...
Phenolic compounds are made of one or more hydroxyl groups directly attached to one or more aromatic rings. Based on the diverse nature of phenolic compounds in foods, they may be classified into simple phenols, hydro...
Phenolic structures often have the potential to strongly interact with proteins, due to their hydrophobic benzenoid rings and hydrogen-bonding potential of the phenolic hydroxyl groups.
