摘要
基于液滴变形模型 ,结合改进的Carnahan Starling方程和适用于描述液滴吸引作用的Hamaker方程建立了一个微乳液体系的状态方程 .运用所建立的状态方程研究了不带电微乳液体系的相平衡性质 ,并计算了十二烷基五氧乙烯醚 正癸烷 水体系O/W型微乳液渗透压以及二 (2 乙基己基 )磺酸基琥珀酸钠 正辛烷 水和二 (2 乙基己基 )磺酸基琥珀酸钠 正癸烷 水体系W/O型微乳液的液液相平衡 ,结果令人满意 .
A thermodynamic equation of state (EOS) for uncharged microemulsion system is established by combining the modified Carnahan-Starling equation and Hamaker equation, which describes the attractive interaction between droplets. By using this EOS, phase equilibrium properties of uncharged microemulsion systems are studied. The osmotic pressures of n-dodecylpentaoxyethylene ether (C12E4)-decane-water microemulsion system are calculated and predicted. The liquid-liquid equilibria volume fractions of sodium bis(2-ethylhexyl)sulfosuccinate (AOT)-octane-water and sodium bis(2-ethylhexyl)sulfosuccinate-decane-water microemulsion systems are calculated. The results are satisfactory.
