Four Different C 8G 1Alkylglucosides. Anomeric Effects and the Influence of Straight vs Branched Hydrocarbon Chains (original) (raw)

phase behavior (6-14), microemulsions (17), and gen-In this work some of the physical-chemical properties of four eral reviews 19). Earlier still, we find articles about the different alkylglucosides are presented. The four alkylglucosides synthesis of AGs. The first real attempt to synthesize AG are 2-ethylhexyl a-D-glucoside, 2-ethylhexyl b-D-glucoside, n-ocsurfactants was performed in 1938 , but as early as tyl a-D-glucoside, and n-octyl b-D-glucoside. Two questions are in 1893, Fisher (21) discussed how to methylate glucose addressed. The first concerns the general influence on surfactant molecules. properties of the type of linkage, a or b, between the glucose head AGs consist of one or several glucose molecules which group and the surfactant tail. The second question concerns the constitute the hydrophilic headgroup and a hydrocarbon difference in properties between straight and branched hydrocarchain that can be either straight or branched, which constibon chains. The binary phase diagrams (temperature vs concentration) and the properties of the one-phase regions have been deter-tutes the hydrophobic tail of the surfactant. The two parts mined. In the micellar regions, 1 H NMR self-diffusion experiments are linked together by a glucosidic linkage (22-24).
