摘要：

In this study, cationic surfactants were synthesized to improve solubility in water by adding ethylene oxide as a hydrophilic group to the intermediates of di-hydroxyl cationic surfactant molecules. The structure of resulting product was elucidated by H-1 NMR, FT-IR and HR/MS. The CMCs of BA-2-MA and BA-5-MA surfactants were found to be 9.01 x 10(-4) and 4.92 x 10(-3) mol/L respectively and the surface tensions at their CMC conditions were 28.64 and 32.22 mN/m respectively. The interfacial tensions measured between 1 wt% surfactant solution and n-decane were found to be in the same order of magnitude as those exhibited between micellar solutions and nonpolar oils.
