Ethylammonium nitrate (EAN) and propylammonium nitrate (PAN) ionic liquids confined between polar glass plates and exposed to a strong magnetic field of 9.4 T demonstrate gradually slowing diffusivity, a process that can be reversed by removing the sample from the magnetic field. The process can be described well by the Avrami equation, which is typical for autocatalytic (particularly, nucleation controlled) processes. The transition can be stopped by freezing the sample. Cooling and heating investigations showed differences in the freezing and melting behavior of the sample depending on whether it had been exposed to the magnetic field. After exposure to the magnetic field, the sample demonstrated decrease in the ¹H NMR signal of residual water. ¹H NMR spectroscopy with presaturation demonstrates that the most probable mechanism of the decrease of the bulk water signal is adsorption of water on polar surfaces of glass plates. Generally, our findings confirm our previous suggestion that alteration of the dynamic properties of confined alkylammonium nitrate ionic liquids exposed to a magnetic field is related to the alteration of real physical-chemical phases.

被限制在极性玻璃板之间并暴露于9.4 T强磁场的硝酸乙铵（EAN）和硝酸丙铵（PAN）离子液体表现出逐渐减慢的扩散率，这一过程可以通过从磁场中移出样品来逆转。该过程可以通过Avrami方程很好地描述，该方程对于自动催化（特别是成核控制）过程是典型的。可以通过冻结样品来停止过渡。冷却和加热研究表明，样品的冷冻和熔化行为有所不同，具体取决于样品是否已暴露于磁场中。暴露于磁场后，样品显示残留水的¹ H NMR信号降低。^1个具有预饱和的1​​ H NMR光谱表明，减少大量水信号的最可能机理是水在玻璃板极性表面上的吸附。通常，我们的发现证实了我们以前的建议，即受限的硝酸硝酸烷基铵铵离子液体的动态特性的变化与真实物理化学相的变化有关。
