On the properties and structure of 2-hydroxyethylammonium formate ionic liquid

On the volumetric properties of 2-hydroxy ethylammonium formate ionic liquid under high-pressures: Measurement and molecular dynamics

“…After that, the water contents of 2-HEAF were investigated using a coulometric Karl Fischer titrator DL 39 (Mettler Toledo) [22]. The results for the NMR spectra have also been reported earlier [21].…”

“…This work is the continuation of our attempt to study of physiochemical property data of 2-HEAF. The aim is to report not only new measurements for density data of 2-HEAF but also molecular dynamic considerations, for which only one effort has been yet reported only under ambient condition [21]. The experimental results for the atmospheric densities (at 0.1 MPa) are going to be compared with the previously reported measurements [16,24].…”

“…Although several efforts have yet been reported on the measurement of density data of pure 2-HEA, all of which were limited to the ambient conditions or atmospheric pressure. An extensive literature survey of the previous efforts is available in the recent work of Hosseini et al [21]. The atmospheric densities of 2-HEAF have yet been measured by the use of several apparatuses from non-digital ones like pycnometer [16] to those were based on the digital apparatus like vibrating-tube densimeter [17,[22][23][24].…”

“…The details of the Preparation of the ionic liquid (2-hydroxy ethyl ammonium formate) have been previously discussed [21]. Also, in order to reduce water content of IL to at least magnitude, vacuum drying was performed for 24 h at 80° C was by the use of a vacuum oven.…”

Separation of azeotropic mixtures using protic ionic liquids as extraction solvents

“…These properties are very interesting in extraction solvents because it can enhance the separation capacity of these compounds. Recently, PILs, like 2hydroxyethylamonium formate, have received a great attention due to the low costs of synthesis, environmentally friendly nature and suitable solvation properties [8][9].…”
