“…24 This DES, based on TEMACl and imidazole, remained liquid, albeit highly viscose, even at -24 °C, while the DES based on imidazole and choline chloride has been reported to have a melting point of 56 °C with the same molar ratio as was used here. 25 Because of its easy preparation from commercially available chemicals and its improved liquid range (according to the supplier, the melting points of imidazole and TEMACl are 88-91 °C and 282-284 °C respectively), this DES was chosen as a potential reaction medium for the succinylation of GWP. Both chemicals are also considered safe, and imidazole has previously been investigated as a green solvent for the dissolution of starch 26 and a recyclable solvent in biomass fractionation.…”
