Abstract—The effects of temperature and aliphatic alcohol on the microemulsification of water in toluene
solutions of bis(2-ethylhexyl)phosphoric acid salts were considered. Viscosimetry and photon-correlation spec-
troscopy were applied to show the effect of the composition of the system on the size of microemulsion drop-
lets. Possible causes of variation in the conductivity of the investigated systems as a function of their composi-
tions were discussed.
