摘要: 用微量热法研究了由正十六烷/正己醇/水/烷基聚氧乙烯醚组成的微乳液中水的状态,对微乳液中水的模式对热效应的影响进行了解释.在微乳液具有异常流变性的水油比范围内,测定了体系在负触变性状态恢复期间的热效应.

Abstract: The heat effect of microemulsion, which is composed of AEO9, hexadecane,hexanol and water was studied by using a 2277 Thermal Activity Monitor.Enthalpic studies onthe state of water microemulsion system have been carried out at 303 K.The resultsindicated that some modification of the three state modes was made.The heat effect of nonionicmicroemulsion was far lower than that of ionic microemulsion.In the unnormal rheologywater/oil ratio region, the thermal effect was determined.The △H*~T curves of differentwater and oil volume ratio were established.

Key words: Enthalpy, Microemulsion, Nonionic surfactant
