金属离子和正辛醇对二(2-乙基己基)磷酸钠微乳体系相行为的影响

Effect of Metal Ion and n-octanol on the Phase Behavior in Microemulsion System of Sodium Di(2-ethylhexyl)phosphate

对于由二(2 乙基己基)磷酸钠(NaDEHP)、正辛烷、水、金属盐和正辛醇组成的微乳体系,研究了金属离子(Na+,Ca2+,Mn2+,Fe3+,Co2+,Ni2+,Cu2+,Zn2+,Al3+)和正辛醇对相行为的影响。当金属盐或正辛醇含量增加时,体系发生WinsorⅠ→Ⅲ→Ⅱ型转变。在影响微乳体系相行为中起主要作用的是金属 HDEHP配合物的亲油性。

The effects of metal ion(Na+,Ca2+,Mn2+,Fe3+,Co2+,Ni2+,Cu2+,Zn2+and Al3+) and noctanol on the phase behavior of microemulsion systems consisting sodium di(2ethylhexyl)phosphate (NaDEHP), noctane, water, metal salt and noctanol have been investigated. The transition of Winsor type Ⅰ→Ⅲ→Ⅱ in these systems occurred as content of metal ion or noctanol increased.The hydrobphobicity of metalHDEHP complex play a major role in affecting the phase behavior.
