Physicochemical properties of oleic acid-based partially fluorinated gemini surfactants.
We have developed oleic acid-based partially fluorinated gemini surfactants with carboxylic acid headgroups. The fluorocarbon chain is covalently bound to the terminal carbonyl group of oleic acid via a -CH(2)CH(2)OCO- unit, and the carboxylic acid headgroups are introduced to the cis double bond of oleic acid via -OCOCH(2)CH(2)- units. The aqueous solution properties of these surfactants were ...
متن کاملSynthesis and Properties of Dissymmetric Gemini Surfactants
A series of novel dissymmetric gemini cationics surfactants was synthesized by three-step reactions. The dissymmetric gemini surfactants contain a dodecanoic acid dimethylethylamine ester as the constant cationic part on one side of the hydroxypropyl center and a similar other cationic part, but with a different acid length (from octanoic to palmitic), on the other side. The critical micelle co...

متن کاملNovel sugar-based gemini surfactants: aggregation properties in aqueous solutiony
Gemini or dimeric surfactants can in principle be viewed as two conventional surfactants connected via a spacer at the level of the polar headgroups. A novel class of sugar-based gemini surfactants with rich and intriguing aggregation behavior in aqueous solution is the focus of this mini-review. The headgroup of the geminis consists of reduced sugars (glucose or mannose) connected to tertiary ...
متن کاملSolution properties and electrospinning of phosphonium gemini surfactants.
Bis(diphenylphosphino)alkanes quantitatively react with excess 1-bromododecane to prepare novel phosphonium gemini surfactants with spacer lengths ranging from 2 to 4 methylenes (12-2/3/4-12P). Dodecyltriphenylphosphonium bromide (DTPP), a monomeric surfactant analog, was readily water soluble, however, in sharp contrast, phosphonium gemini surfactants were poorly soluble in water due to two hy...
