摘　　要：研究了n-CnH2n+1OH(5≤n≤8)对微乳剂透明温度范围的影响。研究结果表明:n值增大,混合表面活性剂含量增加,体系易于形成微乳;当醇及其含量一定时,混合表面活性剂配比对微乳剂的透明温度范围有较大影响;随醇含量增加,微乳剂的透明温度上限降低,下限略有增加;随n值增大,透明温度范围上限温度基本升高,下限温度变化不规律。Effects of n-C.H2n＋1OH （5 ≤n≤ 8） on the transparent temperature region of chlorpyrifos microemulsion were investigated. The results showed that with the increasing of n and the mixed surfactant content, the formation of microemulsion became easier, when the alcohol and its content were constant, the proportion of surfactants had a great influence on the transparent temperature region Of the micro-emulsion, with the increasing of the alcohol content, the upper limit of the transparent temperature declined, and the lower limit of the transparent temperature increased slightly, with the increasing of n, the upper limit of transparent temperature increased mostly, but the changes of the lower limit of transparent temperature had no laws.
