Emerging Heterogeneous Catalysis for Valorization of Biomass‐Derived Platform Molecules: The Systematic Review Toward Sustainable Biorefinery Applications

Advanced Energy and Sustainability Research, Volume 7, Issue 2, February 2026.
Recent advances in heterogeneous catalysis for biomass valorization are highlighted, focusing on furfural, hydroxymethylfurfural (HMF), levulinic acid and glycerol conversion into fuels and chemicals. Metal oxides, zeolites, metal–organic frameworks (MOFs), porous organic polymers (POPs), carbons, and supported metals are compared, emphasizing acid ...

Merging Lignin and Glycerol Carbonate Valorization Toward the Green Synthesis of β‐Adrenergic Blocker Esmolol

ChemSusChem, Volume 19, Issue 1, January 2026.
An atom‐economic methodology toward the synthesis of β‐adrenergic blocker esmolol (1Ha) from sugarcane bagasse has been developed. The depolymerization of sugarcane via a lignin‐first reductive catalytic fractionation catalyzed by Cu20PMO, enables the selective sourcing of methyl(3‐ (3‐hydroxy‐4‐methoxyphenyl)propionate (1H).

Solventless synthesis of solketal with commercially available sulfonic acid based ion exchange resins and their catalytic performance

Green Processing and Synthesis, 2017
As a means to valorize glycerol, the synthesis of solketal through a ketalization reaction with acetone was performed. Mild solventless conditions were applied to test the activity of different commercially available sulfonic ion exchange resins that had

Progress and Challenges of Using Itaconic Acid for Sustainable, Competitive and Advanced Polymers in Additive Manufacturing

Advances in Polymer Technology, Volume 2026, Issue 1, 2026.
Despite efforts to develop polymeric materials using renewable feedstocks, there is a continued reliance on (meth)acrylates for several additive manufacturing (AM) technologies, diminishing their overall sustainability. On the other hand, itaconic acid presents itself as an opportunity to resolve these shortcomings as a biobased source of unsaturation,

Synthesis of Solketal Fuel Additive From Acetone and Glycerol Using CO2 as Switchable Catalyst

Frontiers in Energy Research, 2019
The production of solketal fuel additive was studied from the reaction of glycerol and acetone in the presence of pressurized CO2 as switchable catalyst. A design of experiments (DoE) was used to study the significance of temperature, initial pressure of

Intensification of Ethylene Carbonate Synthesis via Microwave‐Induced Phase‐Change Cycles

ChemSusChem, Volume 18, Issue 19, October 1, 2025.
Microwave‐assisted heating under ambient pressure reflux conditions is applied to intensify the transesterification of ethylene glycol with dimethyl carbonate. The proposed method enhances energy efficiency and product yield compared to conventional heating, enabling lower catalyst loading, reduced process time, and significantly decreased energy ...

Biphasic Continuous Esterification of Choline Chloride‐Based Deep Eutectic Solvents using ICHEM Technology: A Step toward New Hydrotropes with Potential Anticorrosive Properties

Chemistry – A European Journal, Volume 31, Issue 52, September 16, 2025.
Abstract Impact in Continuous Flow Heated Mechanochemistry (ICHEM) technology was used for the first biphasic continuous flow esterification of choline chloride‐based deep eutectic solvents (DESs) with nonmiscible acetic, hexanoic, and octanoic anhydrides, resulting in the synthesis of novel hydrotropic DESs.
