General information
- Short Summary
- The invention of a German university allows non-destructive electrochemical conversion to organic compounds such as carbonyl compounds, but also alcohols, at high energy efficiency and current densities. Its aim is electrochemical biomass refining.The university offers interested companies the option of licensing and refining this technology in collaboration with the inventors.
- Full Description
-
For many electrode materials, carbonyl compounds are electrochemically converted at high reaction rates only in very alkaline or very acidic electrolytes. But these reaction conditions also catalyze aldol condensation and other decomposition reactions in carbonyl compounds, resulting in low yields.
Researchers at a German university have now developed a method that avoids electrode decomposition. It involves placing the aldehyde in an organic, non-polar phase and the hydroxide (an essential reactant) in an aqueous electrolyte. This prevents chemical side reactions in the bulk phase. To perform the electrochemical reaction, a porous, metal-coated membrane is placed at the phase boundary between the two liquids as an electrode. At the three-phase boundary thus formed, the electrode has access to both reactants and can selectively convert the aldehydes into carboxylic acid in a non-destructive manner. For example, HMF from cellulose can be oxidated into FDCA instead of terephthalic acid, which normally comes from oil.
Experiments in the use of the three-phase electrode for butanal oxidation have been performed and analyzed.
The university offers interested companies the option of licensing and refining this technology in collaboration with the inventors.
This invention is primarily aimed at companies from the chemical industry, in particular companies involved in the refinement of electrochemical biomass and catalytic membranes. - Advantages and Innovations
-
Today, many materials are still produced from petrochemical basic materials. Climate change has made a shift to bio-based recyclable materials desirable. As refinement of biomass into important basic chemicals becomes more effective, interest in regenerable raw materials grows.
Further advantages are:
Good yields
Refinement of basic materials from biomass
Fewer secondary products
High current densities - Stage of Development
- Lab tested
- Sustainable Development Goals
- Goal 9: Industry, Innovation and Infrastructure
- IPR status
- IPR applied but not yet granted
- IPR notes
- A patent application has been submitted to the German Patent and Trade Mark Office. Within the priority year, other international applications can be submitted abroad.
