Hydrogen peroxide as a green oxidant for transforming biorenewable carbohydrates into organic chemicals of industrial significance
Biorefinery processes continue to seek sustainable reagents for organic transformations, especially for redox reactions. The liquid-phase oxidation reactions employing aqueous hydrogen peroxide (AQHP) do not necessitate an overpressure of gaseous oxidants, require relatively mild conditions, and produce water and oxygen as innocuous byproducts. AQHP is increasingly used in biomass value-addition pathways, often in the presence of a suitable homogeneous or heterogeneous catalyst, for faster kinetics and improved selectivity. This work gives an account of the recent developments in using AQHP as a green oxidant to convert carbohydrates or carbohydrate-derived chemical intermediates into organic chemicals of industrial significance under chemocatalytic and chemoenzymatic conditions. Mechanistic insights, selectivity, and scalability of the oxidation reactions of carbohydrates and carbohydrate-derived chemical building blocks involving AQHP have been elaborated. The prospects and challenges associated with carbohydrate-centric biorefinery processes using AQHP as a green oxidant have been highlighted.
期刊介绍:
The journal includes papers in the following areas:
– Simple organic liquids and mixtures
– Ionic liquids
– Surfactant solutions (including micelles and vesicles) and liquid interfaces
– Colloidal solutions and nanoparticles
– Thermotropic and lyotropic liquid crystals
– Ferrofluids
– Water, aqueous solutions and other hydrogen-bonded liquids
– Lubricants, polymer solutions and melts
– Molten metals and salts
– Phase transitions and critical phenomena in liquids and confined fluids
– Self assembly in complex liquids.– Biomolecules in solution
The emphasis is on the molecular (or microscopic) understanding of particular liquids or liquid systems, especially concerning structure, dynamics and intermolecular forces. The experimental techniques used may include:
– Conventional spectroscopy (mid-IR and far-IR, Raman, NMR, etc.)
– Non-linear optics and time resolved spectroscopy (psec, fsec, asec, ISRS, etc.)
– Light scattering (Rayleigh, Brillouin, PCS, etc.)
– Dielectric relaxation
– X-ray and neutron scattering and diffraction.
Experimental studies, computer simulations (MD or MC) and analytical theory will be considered for publication; papers just reporting experimental results that do not contribute to the understanding of the fundamentals of molecular and ionic liquids will not be accepted. Only papers of a non-routine nature and advancing the field will be considered for publication.
