摘要： 用二烷基磷(膦)酸钠盐NaA作为阴离子表面活性剂,测定了NaA-醇-油-水体系W/O型微乳液中水的增溶量,用类三元相图确定了单相微乳区,测定了NaDTMPP-HDTMPP-煤油-水(含Na2SO4)体系相的变化,并讨论了溶剂、醇、温度、含盐量等对相行为的影响.

Abstract: The sodium di-alkyl phosphates(phosphonates)NaDEHP,NaEHEHP and NaDTMPP(NaA)used in preserit paper are anionic surfactants.The water solubilization inthe W/O microemulsion systems of NaA-ROH-oil-H2O has been measured;the microemul-sion regions have been determined by means of pseudo-ternary phase diagrams;the thirdphase formation and the transition of Winsor type Ⅰ,Ⅱ,Ⅲ have been investigated underdifferent conditions.The effect of oil,alcohol, salinity and temperature on the phase behavior has been dis-cussed.

Key words: diethylhexyl phosphoric acid, ethylhexyl phosphonic acid mono-ethylhexyl ester, ditrimethylpentyl phosphinic acid, microemulsion, phase behavior
