单体乳化剂的合成及其表面活性的研究

The Synthesis of Monomer-Emulsifer and its Surface Active Properties in Solution

合成了单体乳化剂 4 -( 1 1 -甲基丙烯酰胺基 )十一烷酰胺基苯磺酸钠 [SMAUBS]和乳化剂 4 -十一烷酰胺基苯磺酸钠 [SUABS]。研究了乳化剂的表面活性。测定了 SMAUBS、SUABS的临界胶束浓度分别为 1 .92× 1 0 - 2 mol/L,6.90× 1 0 -

Two emulsifers sodium 4-(11-methacryloyl undecnoyl amino) benzene sulfonate (SMAUBS) and sodium 11-(n-undecylic amino) benzene-sulfonate(SUABS)have been syntesized and it's surface tension in solution have been measured.The results showed that these two emulsifers presented poor surface activity compared with sodium dodecyl benzene sulfonate(SDBS).The critical micellar concentration(cmc) of SMAUBS,SUABS and SDBS are 1.92×10 -2 mol/L,6.90×10 -3 mol/L and 2×10 -3 mol/L,respectivily.
