A method for preparing sugar-based mono and diesters is described. The process entails the esterification of 2,5-furan-dicarboxylic acid (FDCA) with an alcohol in the presence of low loadings of a homogeneous organotin (IV) catalyst.

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.

2,5-Furandicarboxylic acid (FDCA) has received attention as an emerging bio-based building block with many applications, especially in renewable polyesters. The common route to FDCA uses the unstable 5-hydroxymethylfurfural (HMF) as an intermediate. Here, we present an alternative route to FDCA and its esters using C6 aldaric acids as stable intermediates. Aldaric acids, or sugar diacids, can be obtained

The present invention relates to a process for making the esters of 2,5-furandicarboxylic acid, and particularly the dimethyl, diethyl or dipropyl esters of FDCA for use as monomers in the production of polyesters and other types of polymers with biobased content, comprising: reacting an aqueous feed comprising glucaric acid with a high boiling first alcohol in the presence of an acid catalyst and with removing water during the reaction, to form a first product mixture comprising a first ester of FDCA and the high boiling first alcohol; removing unreacted high boiling first alcohol from the first product mixture; combining the first ester of FDCA and the high boiling first alcohol with a lower boiling second alcohol selected from the group consisting of methanol, ethanol, isopropanol and n-propanol; transesterifying the first ester with the lower boiling second alcohol to form a second product mixture comprising a second ester of FDCA with the lower boiling second alcohol; and recovering the second ester of FDCA with the lower boiling second alcohol.
