研究了盐存在下乳化剂/正丁醇-苯乙烯（ St）-水（或盐水）/丙烯酰胺水溶液组成的微乳液的相平衡，发现随着温度的升高，微乳液区间逐渐增大；阴离子乳化剂对微乳液的稳定体系效果更好；适当浓度的盐类物质的加入有利于增大微乳液的聚集数。%The phase diagram of emulsifier / n-butanol - styrene( St)- water( or brine)quasi-ternary system was investigated. The result shows that the microemulsion region increases with the increase of temperature. Anion emulsifier is better for the stabilization of emulsion we studied and salt is benefit for the aggregation number of micro-emulsion.
