Synthesis and properties of lipoamino acid/fatty acid mixtures. Influence of the amphiphilic structure. [PDF]

, 2009
The acylation of amino acids by acid chlorides with from 8 to 12 carbon atoms, in alkaline aqueous medium following Shotten-Baumann reaction, results in sodium salts of Nα-acylamino acids and fatty acids mixture. These lastest are present in proportion

Adsorption Behavior of Fluorocarbon Surfactants on Polytetrafluoroethylene Surface

By using the sessile drop method, the wetting properties of nonionic fluorocarbon surfactants (FNS-1 and FNS-2) and anionic fluorocarbon surfactant (FAS) solutions on the surface of polytetrafluoroethylene (PTFE) were investigated. Meanwhile, the effects

Wettability of a Polymethylmethacrylate Surface by Fluorocarbon Surfactant Solutions

To clarify the adsorption behavior of fluorocarbon surfactants on PMMA surfaces, the contact angles of two nonionic fluorocarbon surfactants (FNS-1 and FNS-2) and an anionic fluorocarbon surfactant (FAS) on polymethylmethacrylate (PMMA) surface were ...

Hyperbranched Hydrocarbon Surfactants Give Fluorocarbon-like Low Surface Energies

, 2016
Two series of Aerosol-OT-analogue surfactants (sulfosuccinate-type di-BCnSS and sulfoglutarate-type di-BCnSG) with hyperbranched alkyl double tails (so-called “hedgehog” groups, carbon number n = 6, 9, 12, and 18) have been synthesized and shown to ...
