Abstract
In this study we innovated microemulsion formula that serve as water in diesel
fuel using minimum amount of commercial and strongly hydrophilic sucrose
monolaurate surfactant (1695) combined with medium chain alcohol. 1-pentanol
has the best effect in enhancing w/o micremulsion region in the pseudo ternary
phase diagrams. Moreover the Phase behavior of sucrose monolaurate (1695) was
studied as a function of temperature and surfactant concentration; that is
presented in the form of the well-known ‘fish’ diagram. Anisotropy was detected
using visual inspection, cross polarizers and polarizing microscope. Water volume
fraction percolation thresholds were determined by studying the electrical
conductivity. The average hydrodynamic diameter of microemulsion measured
using dynamic light scattering equals 10.86 nm at 25°C.
