Abstract
- Graphical abstract Highlights • The solution enthalpies of water in ionic liquids were measured. • The specific interaction enthalpies of water and methanol in ionic liquids were calculated. • The specific interactions enthalpies of water and methanol in ionic liquids are treated as 2:1. Abstract The thermochemical study of hydrogen bonding of water with different proton acceptor ionic liquids was carried out. Along with the available experimental data, the solution enthalpies of water in [BMIM][TfO], [BMIM][BF 4 ] and [BMIM][PF 6 ] were measured. The hydrogen bonding enthalpies of water with various ionic liquids were determined by using previously developed method of solvation enthalpy separation into the nonspecific solvation enthalpy and the specific solute-solvent interaction enthalpy (hydrogen bonding). The findings indicate the formation of a complex, where one molecule of water is bound to two molecules of ionic liquids. Similarly, hydrogen bonding enthalpies of methanol with the same proton acceptor ionic liquids were determined. [ABSTRACT FROM AUTHOR]
