摘要：
(Graph Presented) Microenvironments: Strongly acidic microemulsions are obtained by merely adjusting the water-to-surfactant ratio W in the HOT/isooctane/water system (HOT = H+-exchanged sodium salt of bis(2-ethylhexyl)sulfosuccinate). Acidity functions H0 ranging from H0 = -2 for W = 1 to H0 = 0.5 for W = 30 are determined (see picture). Such acidities cannot be attained by addition of strong acids to the corresponding NaOT-based microemulsions. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
