摘要
以α-烯烃和二苯醚为原料,以固体酸为催化剂合成了双烷基二苯醚双磺酸钠。通过高效液相色谱、核磁氢谱表征了中间体双烷基二苯醚的纯度和结构,通过电喷雾质谱表征了产品结构。考察了双烷基二苯醚双磺酸钠的表面活性、界面活性、润湿性能及外加Na Cl对上述性能的影响。
Sodium dialkylated diphenylether disulfonate（Cn-DADS, n = 8, 10, 12） was synthesized by Friedel-Crafts alkylation of α-olefins and diphenyl oxide with solid acid as catalyst. The purity and the structure of dialkylated diphenylether were characterized by HPLC and NMR. The structure of Cn-DADS was confirmed by electrospray ionization-mass spectrometry. The surface activity, interfacial activity and wettability of Cn-DADS, as well as the effects of Na Cl on these properties, were investigated.
