摘    要:以乙二胺、月桂酰氯、2-溴乙基磺酸钠为原料制备了阴离子型Gemini表面活性剂乙撑-双(N-乙磺酸-十二酰胺)钠盐(简称DTM-12)。以IR和~1H NMR对其结构进行了初步表征,考察了无机盐和醇对DTM-12表面活性的影响。结果表明;DTM-12水溶液的cmc为5.0×10~(-4)mol/L),γ_(cmc)为29.7 mN/m;DTM-12与DTAB组成的复配体系在摩尔比为3:7时,cmc可达1.06×10~(-4)mol/L,γ_(cmc)可达25.4 mN/m,优于十二烷基磺酸钠组成的复配体系。

Abstract:Gemini type ethylene-(N,N′-bis-sodium ethylene sulfonate dodecylamide)(DTM-12)was synthesized from ethylenediamine,lauroyl chloride and 2-Bromoethylene-sulfonate.The structure of the product was characterized with IR and ~1H NMR spectra.The cmc value(5.0×10~(-4)mol/L)of the aqueous solution of DTM-12 was one-sixteenth and one-twentieth as smaller as sodium dodecyl-sul- phate and sodium dodecyl-sulfonate,respectively,and theγ_(cmc)(29.7 mN/m)was also 8-9 mN/m lower than the latter two surfactants.The effects of salt and alcohol on the surface tension of the syn- thesized surfactant were measured.The composite of DTM-12+DTAB with 3:7 moles had better surface activity than sodium dodecyl-sulfonate composite system with cmc value of 1.06×10~(-4)mol/L andγ_(cmc)value of 25.4 mN/m.
Keywords:Gemini surfactant  synthesis  surface activity  composite property
