The depolymerization of natural biomass-based lignin is a definitive challenge, as it involves the integral breakdown complex and well-constructed structures. A sustainable method called ‘ionoSolv pretreatment’ employs ionic liquids in biomass processing. In this study, Bronsted acidic IL (BAIL); 1-methyl-3-(3-sulfopropyl)-imidazolium chloride, [C3SO3HMIM]Cl was synthesized commendably used to ...

BACKGROUND The lignocellulose biorefinery based on the sugar platform usually focuses on polysaccharide bioconversion, while lignin is only burned for energy recovery. Pyrolysis can provide a novel route for the efficient utilization of residual lignin obtained from the enzymatic hydrolysis of lignocellulose. The pyrolysis characteristics of residual lignin are usually significantly affected by...

Due to the increased and excessive consumption of fossil fuels, sustainable alternative energy sources are badly needed replace fuels. The conversion biomass into value-added chemicals is one most promising potential pathways solve this problem. Millions tons lignin, major components biomass, produced annually as a byproduct various industries, where it treated low-value material. However, sinc...

A dithionite-assisted organosolv fractionation process is presented, for the treatment of raw lignocellulose and concomitant production cellulosic pulp reductive conversion lignin into phenolic monomers short oligomers.

Journal: :Biomacromolecules 2021

Biobased materials, derived from biomass building blocks, are essential in the pursuit of sustainable materials. Eugenol, a natural phenol obtained clove oil, but also lignin depolymerization, possesses chemical structure that allows its easy modification to obtain broad and versatile platform biobased monomers. In this Perspective, an overview variety reactions have been executed on allylic do...
