ABSTRACT Two series of lysine glucose ester AOT surfactants and glutamic acid glucose ester Bola surfactants were synthesized, using L-lysine, L-glutamic acid, and α-D-methylglucoside as raw materials. The structures of glucose esters were confirmed by 1H NMR and ESI-MS. Some surface activities were studied, such as cmc, γcmc, C20, Γmax, and Amin. The results showed that cmc decreased, but γcmc increased with the lengthening of hydrophobic chain. The thermodynamic parameters of micellization () indicated that the micellization processes of glucose esters were spontaneous and exothermic, driven by entropy. GRAPHICAL ABSTRACT
