摘要

主要考察了十八烷基三甲基氯化铵(OTAC)和十二烷基硫酸钠(SDS)对油相的增溶规律。通过不同烃类混合

包括两种烃类的混合和4种烃类混合

调整混合油相的等效烷基碳数(EACN)

探索最佳中相醇用量(A*)、最佳增溶量(SP*)与EACN的关系。A*、SP*与EACN在两类表面活性剂条件下都呈现二次函数的关系

且在同一表面活性剂体系中

控制其他组分含量恒定的情况下

函数关系与所用的烃无关。

Abstract

The solubilization behavior of mixed oils was examined using two kinds of surfactants

octadecyl trimethyl ammonium chloride (OTAC) and sodium dodecyl sulfate (SDS). Equivalent alkyl carbon number (EACN) was adjusted through mixing of different kinds of hydrocarbons

including two-component and four-component hydrocarbons. Both of the relations between EACN and the optimum dosage of alcohol (A*) and the relations between EACN and optimal solubilization parameter (SP*) were investigated. It was found that for both of the two kinds of surfactants used in this study

the A* vs EACN and the SP* vs EACN relations fit quadratic functions. For a certain surfactant under constant condition

the quadratic functions were the same no matter what kinds of hydrocarbons were used.
