| 摘 要： | 采用分水时间法考察了结构明确的高纯度烷基芳基磺酸钠在烷烃中的乳化现象。 以液态石蜡为油相，讨论了乳化剂浓度对乳状液稳定性的影响，确定了最适宜的乳化剂浓度，并研究了烷基链长度、芳基结构和芳基在烷基链位置对形成的乳状液稳定性的影响关系，考察了不同油相对乳状液稳定性的影响。 结果表明,最适宜的乳化剂质量分数为0.1%；当固定芳基结构时，随着烷基链上碳数的增加，乳状液稳定性线性增强；当固定烷基链碳数时，随着芳基上碳原子的增加，乳状液稳定性增强；随着芳基位置向烷基链中间位置移动，乳状液稳定性增强；随着油相分子量的增加，能形成稳定乳状液所需的乳化剂的分子量随之递增。

| Abstract: | The abilities of sodium alkyl aryl sulfonate,which had high-purity and defined structure,to emulsify alkanes,were investigated by a water diversion method.Using liquid paraffin wax as the oil phase,the effects of the concentration of emulsion,length of alkyl chain,structures and locations of aryl groups in alkyl chain on emulsion stability were studied,and the best concentration of emulsion were determined.Meanwhile,the effects of different oil phases to emulsion stability were discussed.The experimental da... |
