摘　　要：实验绘制了一系列辛烷基酚聚氧乙烯醚(OP-10) + 醇(正丁醇、异戊醇或正辛醇) + C6H12 + 水(CaCl2水溶液)拟三元体系相图,分别研究了醇的添加比例及CaCl2溶液浓度对微乳区域的影响,发现在纯水的相图中,随着OP-10与正丁醇、异戊醇或正辛醇的质量比逐渐增大,拟三元体系中微乳区的相对面积先增大,后减小;当OP-10:正丁醇 = 1.5:1,OP-10:异戊醇 = 2:1,OP-10:正辛醇 = 2.5:1时,微乳区的相对面积最大。在CaCl2水溶液相图中,三种醇微乳区相对面积总体上呈现先增大后减小的变化趋势,且添加不同醇对微乳区相对面积的影响也不同,其中微乳区面积最大时的正丁醇、异戊醇和正辛醇体系所对应的CaCl2浓度分别为0.1 mol/L、0.5 mol/L和0.1 mol/L。该研究对于拟三元体系相图的绘制、微乳液的配制和微乳法制备纳米材料具有重要的参考价值。A series of quasi ternary phase diagrams of alkyl phenol polyoxyethylene ether (OP-10) + alcohols (n-butanol, isopentyl alcohol or n-octanol) + n-hexane + water (calcium chloride aqueous solution) system have been drawn based on experiments. We investigated the influence of cosurfactant alcohol with different addition and CaCl2 solution with different molar concentrations on the microemulsion region respectively. In pure water quasi-ternary phase diagram, we found that the relative area of microemulsion region in the ternary system increases at the beginning and then decreases with the mass ratios of OP-10 and cosurfactant n-butanol, isopentyl alcohol or n-octanol increase. When the OP-10:n-butanol = 1.5:1, OP-10:isopentyl alcohol = 2:1, and OP-10:n-octanol = 2.5:1, it has the largest area of microemulsion region. In general, the change tendency of microemulsion region relative areas increased at the beginning and then decreased in calcium chloride aqueous solution quasi-ternary phase diagram. The influence of relative area of microemulsion region is also different from adding different alcohols. Among them, the concentrations of CaCl2 with the largest relative area of microemulsion region corresponding to n-butanol, isopentyl alcohol, and n-octanol are 0.1 mol/L, 0.5 mol/L and 0.1 mol/L respectively. This study has important reference value for the drawing of quasi-ternary phase diagram, preparation of microemulsion and synthesis of nanomaterials by microemulsion method.
