A series of anionic gemini surfactants called (oligooxa)-α,ω-bis(m-alkylbenzene sulfonate) with different length in spacer and in hydrophobic chain, C 8 E x C 8 (x=1, 2, 3, 4, 8) and C n E 4 C n (n=8, 10, 12), have been synthesized from 4-n-alkylphenol and their basic physicochemical properties are investigated. The results indicate that they are different...
A novel double chained amphiphile, N-(α-4-hexylphenoxy)-lauroyltaurate (abbreviated as 10+6B-T), has been synthesized. The structures of main intermediate products and the title product were characterized by 1 H NMR. The new amphiphile shows high surface activity. The critical micelle concentration (cmc), which is 1.1×10 −5 mol/L, is much lower than that of conventional double chained...
