An cationi 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 show that the synthetic product is the target product, and its surface tension is 3.4 × 10-4 N/m, and the cmc is 2.2 × 10-4 mol/L at 25 ℃. At the same time, its synergistic effect with common surfactants is studied, the results show that the synthetic product had good syner-gic effect.%用乙烷和十六烷基二甲基叔胺合成了一种阳离子型双子表面活性剂-乙烷-1,2-二(十六烷基二甲基澳化铵),记为16-2-16,并对合成产物进行了表征和理化性能测定.结果表明,合成产物即为目标产物,该双子表面活性剂表面张力为3.4×10-4 N/m,25℃下的cmc为2.2×10-4 mol/L,同时也测定了其与普通常用表面活性剂的复配性能,发现具有优良的复配性能.
