室温离子液体[Emim][PF6]和[Bmim][PF6]压致相变的拉曼散射研究
Pressure-Induced Phase Transition of [Emim][PF6] and [Bmim] [PF6] Studied by Raman Scattering
摘要
Abstract
In-situ pressure-induced phase transition of ionic liquids [Emim] [PF6] and [Bmim] [PF6] have been studied under high pressure and room temperature by usingRaman spectroscopy and highpressure diamond anvil cell (DAC) apparatus.With the increase of pressure,[Emim][PF6] experiences the solid-solid phase transition at about 0.86 GPa,and [Bmim][PF6] experiences the liquid-solid phase transition at about 0.62 GPa and the solid-solid phase transition at about 1.45 GPa.Furthermore,the decrease of pressure of [Bmim] [PF6] has also been discussed in details.Pressure-released Raman spectra shows that the phase transition of [Bmim][PF6] is reversible under pressure up to 2 GPa.关键词
