Bis[N,N′‐(alkylamideethyl)ethyl] triethylenediamine surfactants are quaternary ammonium salt Gemini surfactants with amide, which are synthesized from fatty acid (dodecanoic, hexadecanoic, tetradecanoic and octadecanoic) methyl esters, triethylene tetramine and ethyl bromide. The chemical structures of the prepared compounds were characterized by elemental analysis, FTIR and 1H‐NMR spectra, melting
双[ N,N '-(烷基酰胺乙基)乙基]三亚乙基二胺表面活性剂是具有酰胺的季铵盐双子表面活性剂,由脂肪酸(十二烷酸酯,十六烷酸酯,十四烷酸酯和十八烷酸酯),三亚乙基四胺和乙基溴合成。通过元素分析,FTIR和1表征了所制备化合物的化学结构。H‐NMR spectra, melting point and Krafft point. Several properties of the synthesized surfactants were studied including surface tension, critical micelle concentration, interfacial tension, emulsification power, salt effect, corrosion inhibition efficiency and biological activity.
