氨皂化的P507微乳液导电行为及FT-IR光谱研究

Electrical Conductivity and FT-IR Spectrum of Microemulsion HEHEHP Saponified with Ammonia

利用电导法研究了氨皂化的P507形成的微乳液体系,Ea-VH2O%关系曲线表明,溶水率VH2O%为29%时微乳体系最稳定。利用FT-IR光谱研究了P507皂化时的分子结构变化、微乳液中水的存在形式及微乳液的相变化。增溶水过程发现,P507阴阳离子先发生水化,之后形成微液滴的内相,W/O型微乳液内相增溶水阶段出现渗透现象,再加入水使得分散相联通形成双连续相微乳液,最后发生相变,形成O/W型乳浊液。

The microemulsion contained HEHEHP saponified with ammonia was studied by means of electrical conductivity. The relationship of activation energy （Ea） with water percentage （ VH20% ） in the microemulsion shows that the microemulsion is the most stable as VH20% is 29%. The microstructure of HEHEHP and water existence model in the microemulsion were studied. Study shows that anion and cation of HEHEHP are hydrated at first in the process of water solubilization, then water forms nucleuses of droplets and W/O type microemulsion is shaped. After that percolation of cation within droplets takes place with more water addition. Finally the continuous phase of water is formed and the microemulsion transfers into O/W type microemulsion.
