Abstract
According to an example aspect of the present invention, there is provided a method of producing furan carboxylates from aldaric acids in the presence of a solid heterogeneous catalyst and a solvent with short reaction time. The feedstock for the production is a stable compound, which allows industrial scaling of the process. Solid acid catalyst and sustainable solvent provide considerable reduction of toxic waste compared to traditional methods, and recyclability.
