十二烷基苯醚磺酸盐的合成与表面性能研究

Synthesis and Properties of Linear Dodecylldiphenylether Sulfonates

介绍了在实验室中合成高纯度的十二烷基苯醚单磺酸钠 (MAMS)和十二烷基苯醚双磺酸钠 (MADS)的方法 ,测定了它们各自的及混合物的表面活性。实验结果表明 ,MAMS具有非常低的CMC值 (6 5 3× 10 -6mol·L-1)和γCMC值 (2 9mN/m ) ,MADS的CMC值和γCMC值相对较高 。

This paper concerned the preparation and properties of the linear decyldiphenylether sulfonates. The sodium monodecyldiphenylether monosulfonate(MAMS)and the sodium monodecyldiphenylether disulfonate(MADS) have been prepared. The surface tensions and critical micelle concentrations(CMC) of MAMS,MADS and their mixtures have been measured. The MAMS has very low CMC value(653×10 -6 mol·L -1 )in aqueous 01N NaCl solution, and has very low γ CMC value(29mN/m). MADS has comparatively high CMC value(18×10...
