In order to uncover the micro-structural heterogeneities in the solutions of ammonium-based ionic liquids, diethylamine acetate (DEAA) has been synthesized and concentration-dependent1H NMR spectra of three binary solutions, namely DEAA/water, DEAA/DMSO and DEAA/acetone, at different compositions have been measured at 298.15 K. The proton chemical shifts of DEAA have been correlated using the1H NMR local composition (LC) model. It has been found that the self-associations of DEAA were predominant instead of DEAA–solvent interactions within DEAA-rich region. However within solvent-rich region, DEAA could mainly interact with solvent molecules, indicating that the network of DEAA has been greatly destroyed by effects of solvents. In addition, the ability of solvents to break down the structure of DEAA followed in such order: water > DMSO > acetone, which was consistent with changes of physicochemical properties of these solutions.
