Phase Behavior and Structural Transitions in Fenvalerate Microemulsion
Abstract:
Pseudo ternary phase diagrams of fenvalerate microemulsion are presented.The mechanism of fenvalerate microemulsion formation was studied,with the particular emphasis on the effects of different temperature and different alcohols on fenvalerate microemulsion formation.It has been found that the type and area of microemulsion region vary with the length of carbon chain of alcohol molecules.The microemulsion region increases with the increase of temperature for the same cosurfactant (n-butanol).Microstructure was studied by means of conductivity measurement.When the mass ratio of surfactant solution (S+A) to fenvalerate solution (O+A) was 4:1,the microstructure changed from W/O structure through bicontinuous structure to O/W structure.When the mass ratio of (S+A) to (O+A) was 6:4,there was a liquid crystal region before bicontinuous structure.
