摘要
绘制了复合表面活性剂(D0821/Tx-4/AEO-3)/正戊醇/柴油/水体系在不同温度及不同正戊醇质量分数时的一系列拟三元相图。结果表明,正戊醇质量分数及温度对拟三元相图及水最大增溶量有很大影响,醇量太大或太小形成的微乳区面积均较小;温度升高,微乳区面积及水最大增溶量也大大减少;随着正戊醇质量分数的增大,每一个温度下的微乳区及其最大增溶水量都逐渐向AEO-3/正戊醇/油角漂移。
Phase diagrams of pseudo-ternary microemulsions consisting of mixed surfactants (D0821/Tx-4/AEO-3)/n-pentanol/diesel oil/water system were plotted at different temperatures and different mass fractions of n-pentanol,and the properties of microemulsion system were discussed.The results show that area of microemulsion regions and maximum water content of microemulsion are related to mass fraction of n-pentanol and temperature.We got the largest area of microemulsion regions when the mass fraction of n-pentanol is proper.In addition,area of microemulsion region and maximum water content of microemulsion decreases with increase in temperature.The microemulsion region and maximum water content of microemulsion move to the corner (AEO-3/n-pentanol/diesel oil) in the phase diagram with increasing mass fraction of n-pentanol.
