辛基苯基聚氧乙烯醚硫酸钠与溴化烷基吡啶的相互作用研究

THE INTERACTION BETWEEN SODIUM OCTYLPHENY-LPOLYOXYETHYLENE SULFATE AND BROMIDE ALKYL PYRIDINIUM

利用表面张力法和紫外光谱法研究了辛基苯基聚氧乙烯醚硫酸钠Ｃ＿８Ｈ＿（１７）Ｃ＿６Ｈ＿４（ＯＣ＿２Ｈ＿４）＿（１０）ＯＳＯ＿３Ｎａ与嗅化烷基吡啶ＣｎＨ＿（２ｎ＋１）ＮＣ＿５Ｂｒ（Ｃｎｐ＿ｙ，ｎ＝１２，１４，１６）的相互作用。结果表明，具有很高的表面活性，二者是由的硫酸头与ＣｎＰｙ的吡啶头间的相互作用引起的。但其硫酸头与吡啶头间未发生电性中和，这可能是形成均相水溶液的原因之一。

The interaction between Sodium Octylphenylpolyoxyethylene Sulfate C_8H_(17)C_6H_4(OC_2H_4)_(10)OSO_3Na and bromide alkyl pyridinium CnH_(2n+1)NC_5H_5Br(CnPY;n= 12,14,16) has been studied with surface tension method and UV-spectrum method The results show that the surface activity of is very high as there is a strong interaction between and CnPy. There is only one indirect attraction between the sulfate head of S and pyridinium head of CnPy,which may be one of the reasons why the aqueous solution of is homogeneous.
