Tendencies of Solid Phase Formation in Deep Eutectic Solvents of Betaine and Xylitol

This proceedings article and the poster report experimental investigation of betaine blends with xylitol.  Betaine mixtures with 60-65%wt. xylitol can liquefy without any chemical reaction and retain fluidity for prolonged durations. Mixtures outside this ratio are not as stable and might form excessive solids. Measurement of melting or freezing points might not be appropriate when supercooling effects are significant. Solids formation should be monitored. Formation of small amounts of solids on the DES surface could not be avoided. Effects of humidity should be considered.This study was carried out under project TERMINUS, funded by the European Union under Horizon 2020. Call: H2020-NMBP-ST-IND-2018.  Grant Agreement: 814400.
