Preparation of a new BTEAB/DMSO deep eutectic solvent for highly efficient starch dissolution and succinylation

Year: 2026

Type: article

Abstract: NMR, XRD, SEM, EDX, and TGA, confirmed substantial modification of starch after treatment. The regenerated material exhibited a marked loss of crystallinity, the disappearance of native granules, changes in elemental composition, and a decrease in thermal stability, all of which are consistent with successful incorporation of succinyl groups. These results clearly demonstrate that the BTEAB/DMSO DES is not only a powerful solvent but also an effective reaction platform for starch valorization. Overall, this study introduces a highly promising, eco-friendly strategy for polysaccharide processing and opens new avenues for sustainable chemical transformations based on DES.
