Effects of self-hydrogen bonding among formamide molecules on the UCST-type liquid–liquid phase separation of binary solutions with imidazolium-based ionic liquid, [C n mim][TFSI], studied by NMR, IR, MD simulations, and SANS
Résumé
The UCST of phase separation for imidazolium-based ionic liquids [C n mim][TFSI] and formamide (FA) binary solutions increases with elongation of the alkyl chain length n . This is opposite to previous 1,4-dioxane solutions.
