摘　　要：采用称重法绘制十六烷基三甲基溴化铵、异丁醇、正己烷和过碳酰胺水溶液的拟三元体系相图,电导率法确定微乳液的区域。在水包油区域内,采用HPLC定量检测技术,研究微乳液组分含量变化对甲基苯基硫醚降解反应速率的影响。结果表明:甲基苯基硫醚在微乳液中的反应符合一级反应动力学规律。过碳酰胺质量分数达到3.75%时,甲基苯基硫醚的反应速率不再随体系中过碳酰胺含量的增加而变化。当表面活性剂与助表面活性剂比值一定,水含量恒定时,反应速率随正己烷含量的增加而减小;正己烷含量恒定,反应速率随水含量的增加而增加。The pseudoternary phase diagram of cetyl trimethyl ammonium bromide,isobutanol,n-hexane and percarbamide aqueous solution were drawn by weighing method,and regions of microemulsion were determinated by measuring the conductivity of the systems.The effects of compositions content of microemulsion on the degradation rate of methyl phenyl sulfide were studied in the oil in water area by HPLC.The results showed that the reaction of methyl phenyl sulfide in microemulsion accorded with the first-order reaction.When the mass content of percarbamide reached a certain value(3.75%),the reaction rate of methyl phenyl sulfide no longer changes with the increase of percarbamide.When the ratio of surfactant and cosurfactant was fixed and the water content was constant,the degradation rate of methyl phenyl sulfide decreases with the increase of n-hexane.When the mass percents of n-hexane was constant,the reaction rate increased with the increase of water.
