| 摘 要： | 试验发现，由Ca(OH)2饱和水溶液、油酸的煤油溶液和CTAB水溶液组成的W1／O／W2三相体系，其油水界面产生了pH、电势及电导率的不规则振荡。通过组份替换和添加物的比较，解释了产生振荡的原因和机理。振荡产生于油酸与钙碱之间的成皂反应。其生成的表面活性剂-钙皂为关键组份，CTAB是主要助剂。反应结束后，通以交流电，还发现了可逆振荡现象，并据乳液性能进行了解释。

| Abstract: | It was found from experiment that irregular oscillations of pH,electric potential and conductivity were produced at the interface between oil and water in the W_1/O/W_2 three phases system consisted with saturation Ca(OH)_2 aqueous,kerosene solution of oleic acid and CTAB aqueous.The mechanism was explained by substitution of components and comparison of additives.The oscillations were produced from becoming soap reaction between oleic acid and calcium alkali.Its product of surfactant-calcium soap was key component and CTAB was main assistants.The reversible property of the oscillation was also discovered with electrifying alternating current on the system after the reaction.And it can be explained by the changes of emulsion formation and break. |
