摘要

研究了水-乙醇-汽油液-液平衡。在本研究中，在KH2PO4、KCl和KOH的影响下，通过浊度滴定法以重量和体积法获得LLE数据。在30°C和50°C时也评估了温度的影响。结果表明，离子的存在改变了LLE，不同离子对LLE的影响不同。在浓度为20 mM时，温度对LLE有显著影响。温度升高，非均相区减小，汽油相中水分增多。

Influence of Ions and Temperatures on Water-Ethanol-Gasoline Liquid-Liquid Equilibrium

Water-ethanol-gasoline liquid-liquid equilibrium (LLE) was investigated. In this study, the LLE data was obtained gravimetrically and volumetrically by turbidity titration under influence of KH2PO4, KCl, and KOH. Effect of temperature was also evaluated at 30 and 50°C. Results suggest that presence of ions alter the LLE and different ions affect the LLE differently. At concentration of 20 mM, temperature had significant effect on the LLE. Increasing temperature reduced the heterogeneous region and allowed more water in gasoline phase.
