摘　　要：制备了双酸性离子液体并对其进行表征,探讨了其水溶液不同温度和浓度条件下的表面张力和折光率。结果表明,双酸性离子液体水溶液的表面张力和折光率受含水量和温度的影响。随着含水量的增加,表面张力呈增加趋势,折光率则与之相反;随着温度升高,折光率和表面张力都呈下降趋势。A dual acidic ionic liquid was prepared and characterized,and the surface tension and refractive index of its aqueous solution were investigated under different temperature and concentration conditions.The results indicate that the surface tension and refractive index of aqueous solutions of dual acidic ionic liquids are affected by water content and temperature.As the water content increases,the surface tension shows an increasing trend,while the refractive index is the opposite.As the temperature increases,both refractive index and surface tension show a decreasing trend.
