摘要

采用加溶法研究了由阴离子型表面活性剂直链烷基磺酸钠 Cn H2 n+1SO3Na( n=8

14) -正烷烃 -正已醇 -水组成的四组分微乳液

探论了微乳液体系不同含水量时烷烃链长、表面活性剂链长和盐浓度对正已醇从油相转移至界面相对自由能 -△ Goo→ i变化的影响

发现自由能 -△ Goo→ i与烷烃链长有线性关系

但含水量不同

烷烃链长对自由能 -△ Goo→ i的影响不同

含水量越高

烷烃链长影响越大 ;在盐浓度为 O- 0 .12 mol/ L范围时自由能 -△ Goo→ i与盐浓度有线性关系

但不同含水量时盐对自由能 -△ Goo→ i的影响不同

含水量越低

盐浓度的影响越大 ;烷烃为正辛烷时

自由能 -△ Goo→ i与表面活性剂的链长有线性关系

但不同含水量时表面活性剂的链长对自由能 -△ Goo→ i的影响不同

含水量越低

表面活性剂的链长的影响越大 .这方面的研究对我们认识微乳液的结构和稳定性十分重要 .

Abstract

The microemulsion is composed of linear alkyl sulfonate(C nH 2n+1 SO 3Na

(n=8

14)

oil(alkane)

water(brine)

and alcohol.The system was studied thermodynamically by means of dilution to determine the standard free energy(-△G o o→i )for alcohol to transfer oil phase in interfacial region.At various water content in the systems

the effect of chain length of alkane and surfactants and salt are described.It is found thant the standard free energy change linearly with the increase of the number of carbon in alkane and surfactant

but water content in the system influence the change of the standard free energy with the increase of the number of carbon in alkane and surfactant.Another

the standard free energy change linearly with the increase of salt(NaCl)concentration (0～0.12 mol/L)at various water content in the system.The water content influences the change of the standard free energy with the increase of salt concentration.It is important for us to understand the structure and stability of microemulsion.
