Ozonólise das ligninas organossolve e kraft eucalipto. Parte II: cinética nos meios ácido e básico Ozonolysis of organosolv and kraft eucalyptus lignins. Parte II: kinetic in basic and acid media

Química Nova, 1998
Organosolv and kraft lignins were treated with ozone both in basic and acid media and the reaction was studied kinetically. In contrast to reported studies, ozone was more efective in basic medium.

The effect of organosolv pretreatment on the enzymatic hydrolysis of poplar [PDF]

Biotechnology and Bioengineering, 1984
AbstractThe use of alcohol/water/catalyst mixtures to delignify wood allows the lignin to be recovered in a usable form while leaving the carbohydrate fraction relatively intact. The effects of temperature, reaction time, and the type of solvent and catalyst on the delignification of milled poplar wood were investigated.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Two step fractionation of oil palm empty fruit bunches integrating hydrothermal-organosolv pretreatment for enhanced lignin extraction and enzymatic hydrolysis efficiency

Case Studies in Chemical and Environmental Engineering
Lignocellulosic biomass, consisting of cellulose, hemicellulose, and lignin, represents a sustainable alternative to fossil fuel resources. However, its full utilization remains unexplored, as many studies have focused on recovery only one or two ...

Reaction Characteristics of Organosolv-Fractionation Process for Selective Extraction of Carbohydrates and Lignin from Rice Husks

Energies, 2021
The organosolv-fractionation process can act as a biorefinery process because it can separate the main components of biomass, such as lignin and hemicellulose, with high purity.
