Abstract: In reverse microemulsions, sodium bis(2-ethylhexyl) sulfosuccinate(Aerosol OT, AOT) has an ability to solubilize much larger amount of water than dimethyl sulfoxide(DMSO), formamide and acetonitrile(the amount of the polar solvent solubilized in AOT reverse microemulsions: water >acetonitrile >formamide >DMSO). In the microemulsions with the mixtures of nonaqueous polar solvent and water as polar phases, the solubilization of formamide and acetonitrile is in antagonism to that of water, while the presence of water in a certain extent increases the solubilized amount of DMSO. The influences of various polar solvents on the conductivity properties of the reverse microemulsions have been studied.

Key words: Nonaqueous reverse microemulsions, DMSO, Formamide, Acetonitrile,  Solubilization, Conductivity
