Abstract: In the organic phase of saponated P507(2-ethylhexylphosphonic acid mono-2-ethyl-hexyl ester) the formation of reversed micelle and microemulsion in the process of titration with water has been studied by calorimetry method.The critical micelle concentration (CMC),aggregation number (n),formation constant(K) and thermodynamic function of micellization were determined.The hydro-dynamic radius of each droplet was also obtained by the laser light scattering experiment.

Key words: Titration calorimetry, Solvent extraction, Microemulsion, Reversed micelle
