The Interfacial Tension Between Cationic Gemini Surfactant Solution and Crude Oil
Aug 01, 2009; ... Abstract The effects of the hydrocarbon chains and spacer groups of gemini surfactants, salt, temperature, and polymer on the interfacial tension of crude oil-water mixtures were investigated in this paper. The length of the alkyl chain is a major factor affecting the properties of a ...
Bifunctional N-Oxides of Alkyldiamidoamines
Aug 01, 2009; ... Abstract A homologous series of new surface-active 1,1-bis{[3-(N,N-dimethylamino)ethyl]-amido}alkane-di-N-oxides were synthesized in the reaction of an appropriate diethyl 2-alkylmalonate with N,N-dimethylethylenediamine followed by oxidation with an aqueous solution of hydrogen ...
Design of Experiments to Evaluate the Detergency of Surfactants on Fatty Soils in a Continuous-Flow Device
Aug 01, 2009; ... Abstract Detersive processes are complex systems involving a great number of variables. To determine the effect of these variables on the washing of hard surfaces and fatty soils is the object of this work. The statistical design of experiments has been used to evaluate the influence of ...
Solubilization and Adsolubilization of Polar and Nonpolar Organic Solutes by Linker Molecules and Extended Surfactants
Aug 01, 2009; ... Abstract Adsolubilization reaches its maximum when a surfactant adsorbed onto the solid-liquid interface achieves complete bilayer or maximum adsorption. The attempt to enhance the adsolubilization of organic solute is accomplished by increasing interaction between the hydrophobic core ...
A Rheological Approach to Viscoelastic Worm-Like Micelles of Tunable Properties
Aug 01, 2009; ... Abstract The rheological behavior of micellar solutions of cationic surfactant, cetyl trimethyl ammonium bromide in the presence of a salt (KBr) and a co-surfactant (n-octanol) were analyzed. Shear viscosity and shear moduli were measured as a function of concentrations of the ...
