【摘要】 研究了若干非水极性溶剂(甲酰胺、二甲基亚砜和乙腈)及其与水的混合物/AOT/正庚烷反相微乳体系的加溶性质及其电导行为.结果表明,在AOT反相微乳中,非水极性溶剂的最大加溶量均远小于水的加溶量.其最大加溶量顺序为二甲基亚砜<甲酰胺<乙腈<水.甲酰胺和乙腈与水的加溶相互抵制,而水在一定范围内可促进二甲基亚砜的加溶.非水反相微乳的电导率随加溶量的变化规律与含水反相微乳体系类同,但到达电导率极大值和出现渗滤时的加溶量明显比含水反相微乳体系的要小.更多还原

【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.更多还原
