磺酸盐型 Gemini 表面活性剂复配体系的黏度性质研究
Study on the viscosity characteristics of blend surfactant system containing sulfonate type Gemini surfactant
摘要
Abstract
Evaluation of surface activity of a sulfonate type Gemini surfactant made of 1 - bromotetradecane, ethylenediamine and 1,3 - propane sultone was conducted. Effects of separate addition of quaternary ammonium salts (QASs)with different carbon chain length,inorganic salts,and organic salt,as well as shearing time period and temperature on the viscosity characteristics of the blend surfactant system containing the abovesaid sulfonate type Gemini surfactant were emphatically investigated. The results showed that the critical micelle concentration of above - mentioned surfactant is lower 1 ~ 2 order of magnitude than that of the corresponding single chain surfactant. When QASs is added into the sulfonate type Gemini surfactant aqueous solution of mass fraction of 1%,the viscosity of the blend surfactant system increases firstly;and the longer the carbon chain length of the QASs,the more obvious the viscosity increase effect;while up to a maximum value of 245. 5 mPa·s,then it declines. Increase of the length of carbon chain helps the formation of wormlike micelles. The separate addition of KCl,NaCl and sodium salicylate all can increase the viscosity of the blend system composed of the sulfonate type Gemini surfactant and cetyltrimethylammonium bromide (CTAB)firstly and then decline. Among them, the most obvious one is KCl. When its mass fraction achieves 0. 12%,the viscosity increases to a maximum value of 430. 2 mPa·s. Following the increase of shearing time period and temperature,the viscosity of the blend system declines.关键词
