A novel homologous series of 1-N-L-phenylalanine-glycerol ether surfactants was synthesized in satisfactory yields via reaction of epichlorohydrin with aliphatic alcohols with alkyl chains of 10-15 carbon atoms. Structural assignment of the new compounds was made on the basis of elemental analysis and spectroscopic data. Critical micelle concentration (CMC), surface tension at the CMC (γ CMC ), surfactant concentration required to reduce the surface tension of the solvent by 20 mN/m (pC 20 ), and the interfacial area occupied by the surfactant molecules (A min ) were determined from aqueous surface tension measurements using the Wilhelmy plate technique.
The preparation of microemulsified disperse inkjet inks was carried out and the effect of the surfactant used as dispersing agents on the properties of the inks was studied. The dispersing agents used were anionic conventional and non-conventional surfactants and a gemini type surfactant. The properties studied were surface tension, pH, conductivity, viscosity and the particle size distribution. The use of the gemini type and the two non conventional surfactants even in submultiple amounts resulted in a significant increase in the ink stability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
