Abstract:
4'-fatty amido-3'-sodium carboxylate azobenzene-4-sodium sulfonates were synthesized by coupling, and then acylation reactions. They are proved to be surfactant by determining their surface tensions at various concentrations in aqueous solution, and investigating their adsorption isotherms. Of them the best C16 compound shows relatively good surface activity with gcmc of 49.4mN/m at cmc of 0.024mol/L and gmin of 44.6mN/m. |
