Thermogravimetric measurement of deep eutectic solvents vapor pressure

Vapor Pressure Mapping of Ionic Liquids and Low-Volatility Fluids Using Graded Isothermal Thermogravimetric Analysis

“…The structure-volatility series for the DES mixtures containing choline chloride but with different hydrogen bond donors is ethaline > reline > glyceline (most to least volatile), emphasizing that ethaline is one of the most volatile DESs. This trend agrees with solvent polarity (E T (30) and α) values reported in the literature and TGA experiments conducted by Shahbaz et al [23,49]. Figure S8 shows the temperature dependence of measured values against the Shahbaz data for reline and glyceline.…”

“…The coefficients (a and b) are dependent on the instrument, operational conditions (e.g., gas purge rate), and sample containment procedures [36]. This proportionality is reported to be independent of the sample and the temperature range [13,23,37,38]. Glycerol was used as a reference compound to attain the instrument constants for our TGA instrument (TGA-1) because the P vap data are well-established.…”

Gas solubility and rheological behavior study of betaine and alanine based natural deep eutectic solvents (NADES)

“…Some recent studies hypothesizes that there are some examples of NADES in living organisms and it is believed to lead the biosynthesis of poorly water-soluble metabolites and macromolecules in the aqueous environments [24,41]. NADES are considered as viable alternatives, since they have very low vapor pressure that prevents the solvent losses [42]. Moreover they are much cheaper to produce when compared with exotic solvents as well as ILs, they are biodegradable and biocompatible, which makes their disposal straightforward and inexpensive [21,43].…”

Assessment of the organocatalytic activity of chiral l-Proline-based Deep Eutectic Solvents based on their structural features

“…Born as a "side-class" of ionic liquids, DESs share with them many properties such as: low or absent vapour pressure (that can lead to "out of the hood" procedures, pointing out to economic and environmental advantages); low flammability; high recycle and re-use capabilities, and so on [7][8][9][10]. However, DESs show lower (and in some cases absent) toxicity compared to ionic liquids with lower their environmental, just thanks to their higher biodegradability and to the bioavailability of their components [11][12][13][14].…”
