Hydrogen peroxide as an oxidant in biomass-to-chemical processes of industrial interest

Abstract

H2O2 as a green and liquid alternative of gaseous oxygen creates new strategies for biomass conversion to chemicals.

Metal Catalyst‐Free Oxidative C−C Bond Cleavage of a Lignin Model Compound by H2O2 in Formic acid

“…These pioneering previous studies inspired us to look for a simpler system for C α −C β bond cleavage of β‐O‐4 LMC. In this work, ketone LMC was cleaved directly by H 2 O 2 , a green and liquid oxidant, in formic acid under metal catalyst‐free conditions, and over 85 % product yield was achieved in 4 h at 100 °C. With mineral acid catalyst, the reaction was efficient at room temperature (25 °C) and over 90 % product yield could be obtained in 6 h.…”

Selective dihydroxylation of methyl oleate to methyl-9,10-dihydroxystearate in the presence of a recyclable tungsten based catalyst and hydrogen peroxide

“…26 H2O2 is widely used as oxidant in biomass conversion to chemicals and some examples reported the combination of H2O2 and tungstic acid for fatty acids conversion to dicaboxylic acids, azelaic acid, etc. 27 For example, a high conversion of 90% and 80% selectivity in desired diol during dihydroxylation reaction was observed in the presence of this system. One can mention that a concentrated solution of H2O2 (> 60%) is required and should be added continuously to convert fatty acids.…”

Recent Developments in Heterogeneous Catalytic Routes for the Sustainable Production of Succinic Acid from Biomass Resources

“…Also, the unique chemistry associated with H 2 O 2 , such as the classic Baeyer-Villiger and epoxidation reactions provides additional methods for biomass conversion. [53] The GO catalyst was reusable and its catalytic activity was observed to decrease after six cycles. The aldehyde group was oxidized into a carboxyl group in the absence of catalyst to give 8.1 % yield of furoic acid without any trace of SA, which implied that GO is crucial for SA formation.…”
