Abstract

Abstract: A series of biantennary sugar‐based surfactants reflecting glyco‐glycero‐lipids, in which the ester linkage of the surfactant antipodes was replaced by a triazole, has been synthesized and investigated on their emulsifying potential for water‐in‐oil systems related to hydrofuel. The results suggest beneficial interactions of the triazole with fossil‐derived diesel, whereas corresponding interactions appear to destabilize emulsions in ester‐based biodiesel. The highest emulsion stability was observed for 1, 3‐linked glycerol‐isomers, where the glucose‐based ATG outperformed the corresponding xylose‐analogue exhibiting a significantly higher Krafft temperature. Molecular modeling results relate this behavior to chromonic interactions of the triazole rings. Abstract :
