文摘

Ethylammonium nitrate is strongly associated in mixtures with nitromethane at XEAN ≤ 0.013. At XEAN ≥ 0.4 EAN + nitromethane mixtures behave as “lubricated” ionic liquid. Cooperative dynamics of mixtures and ion association dominated by hydrogen bonding among ions. Ion solvation by nitromethane is weak.
