AI Technical Summary
In the existing technology, the methods for synthesizing high-value chemicals by reacting sugars such as glucose with carbon dioxide have not been fully developed. The production pathways for multi-carbon carboxylic acids are limited, and there is a huge price difference between raw materials and products, with a lack of effective conversion methods.
A catalytic system employing a rhodium catalyst, iodine as a co-catalyst, and a binary solvent composed of carboxylic acids and water generates multicarbon carboxylic acids through a coupling reaction of carbohydrates with carbon dioxide and hydrogen.
This technology enables the conversion of inexpensive renewable resources such as carbohydrates and carbon dioxide into high-value-added multi-carbon carboxylic acids, opening up new avenues for biomass utilization and carbon dioxide conversion. The resulting multi-carbon carboxylic acid product has broad application prospects.
