Synthesis and Evaluation of a New Type of Cationic Gemini Surfactant

摘要

A cationic Gemini surfactant ethane-1, 2-bis (Cetyl dimethyl brominated ammonium), denoted 16-2-16 was synthesized from ethane and Hexadecyl dimethyl amine. The properties of the product were characterized, and the physical and chemical properties were determined. The results showed that the synthetic product was the target product, and its surface tension was 3.4×10~(-4)N/m, and the CMC was 2.2×10~(-4)mol/L at 25?C. At the same time, its synergistic effect with common surfactants was studied; the results showed that the synthetic product had good synergic effect.
