Abstract
The novel anionic surfactant sodium 3-oxo-2-(3-(4-sulphonatophenyl)triaz-2-enyl)octadecanoate (SSTO) was prepared from renewable raw materials; glycine and palmitic acid. Surface and bulk properties of SSTO were investigated by surface tension technique at 298, 308, 318 and 328 K. A series of important parameters including critical micelle concentration (CMC), maximum surface excess concentration (Γmax), minimum area per molecule (Amin), surface tension at CMC (γCMC), effectiveness of surface tension reduction (ΠCMC) and efficiency of surface adsorption (pC20). The effect of 3 wt% n-propanol, n-butanol and n-pentanol was also considered at 298 K.
