摘　　要：通过绘制非离子表面活性剂TX-10／脂肪酸甲酯／正己醇／水体系的拟二元相图,考察了农药丙酯草醚对体系的相行为的影响,发现丙酯草醚对体系相行为影响不大。体系中加入阴离子表面活性剂LAS后,可以形成对温度不敏感的单相透明微乳液。在TX-10与LAS复配体系中,丙酯草醚的加入使形成单相透明微乳液所需表面活性剂浓度增加,起始温度升高,透明温度的范围变窄。The effect of herbicide（ZJ0273） on nonionic surfactant（TX-10）/fatty acid methyl ester/hexanol/ herbicide/water system was studied based on the ＂ fish＂ diagrams. A temperature-insensitive microemulsion was formed with the addition of the anionic surfactant LAS. The total surfactant concentration required to form the single phase microemulsion was increased in the presence of the herbicide. In addition, the temperature required for the formation of transparent single phase microemulsion was omcreased, while the temperature region of the transparent single phase was narrowed by the addition of herbicide.
