Abstract

Microemulsification and blending of commercial diesel is under constant research for possible fuel application. Microemulsions (ME) were prepared using diesel (D), kerosene (K), diesel and kerosene mixtures at various proportions (D + K) (oil phase: O), Triton X-100 surfactant (S), n-butanol, isobutanol (i-butanol), n-pentanol and n-octanol cosurfactants (C), and aqueous phase (W) containing water or brine for the study. Electrical conductance studies and temperature-induced separation of phase have been adopted for recognizing the o/w, w/o and bicontinuous zones. Dye probing has been done to explain the mass transfer among these phases. Percent of solubilization of oil in water has been enumerated in some of the ME. The possible fuel applications of the microemulsions are predicted from their density and flame brightness.
