혼합 계면활성제를 이용한 염소화 탄화수소/물의 마이크로에멀젼 연구 = Microemulsification of Chlorinated Hydrocarbon / Water with Mixed Surfaetant Systems

다국어 초록 (Multilingual Abstract)

The phase behavior of chlorinated hydrocarbon/mixed surfactants/water microemulsion systems were investigated for dry cleaning solvent properties. With appropriate surfactant mixtures, Winsor type I→III→II microemulsions were generated which is the same as hydrocarbon systems. For perchloroethylene(PCE) with mixed Tween systems, the optimum salinity(S^*) decreases and the optimum solubilization parameter(σ^*) increases with decreasing HLB. For PCE with mixed Aerosol MA and ethoxylated alcohol systems, s^* and σ^* both increase with increasing ethylene oxide moles. For dichlorobenzene(DCB) with mixed Aerosol MA and ethoxylated or propoxylated sulfate systems, S^* and σ^* both increase with increasing ethylene oxide moles or propylene oxide moles.
