摘　　要：为了制备能够用于强碱性体系中萃取的微乳液体系,研究了以N263作为表面活性剂,醇类为助表面活性剂,煤油为油相形成的微乳液体系的相行为,考察了表面活性剂浓度、助表面活性剂种类及浓度、内水相盐度及pH、温度等因素对微乳液最大增溶水量的影响,并通过微乳液电导率的测定来考察微乳液的稳定性.结果表明:当N263浓度为10%、异戊醇浓度为25%,内水相浓度为(0.4mol/L NaCl+0.2mol/L NaOH),温度为T=35℃,煤油为油相时所制备的微乳液稳定且增溶水量能到达15%左右.This paper studies the phase behavior of micro-emulsion by using N263 as surfactant alcohols as cosurfactant and kerosene as oil phase.We focus the study on the effects of surfactant concentration,co-surfactant kinds and concentration,inner water phase salinity and pH value,on water content of the micro-emulsion the stability of micro-emulsion is also investigated by measuring the its conductivity.The results shows the microemulsion stays stable and the water content can reach to about 15% under the following conditions： N263 concentration is 10%;isoamyl alcohol concentration is 25%;inner water phase concentration is 0.4mol/L NaCl＋0.2mol/ L NaOH;temperature is 35℃;kerosene used as oil phase.
