Potentiometric titrations have been carried out in the presence of 0.10 M sodium chloride for micellar solutions of two different amine oxide types of surfactants, dimethylalkylamine oxides (DMC nAO) and dihydroxyethylalkylamine oxides (DHC nAO). The surface potentials of the micelles were obtained...
The hydrogen ion titration of long alkyl chain amine oxide micelles was carried out at various salt concentrations, Cs, surfactant concentrations, CD, and temperatures T. The surfactants studied were alkyldimethylamine oxides (CnDAO) with hydrocarbon chain lengths of 10–16 (n=10, 12, 14, and ...
silica and/or metal oxides such as alumina. The latter may be either naturally occurring or in the form of gelatinous precipitates or gels including mixtures of silica and metal oxides. Use of a meterial in conjunction with the catalyst zeolite, i.e., combined therwith or present during it...
The present invention provides novel fuel-soluble very long chain alkylphenyl polyoxyalkylene amine fuel additives which are useful for the prevention and control of engine deposits, particularly intake valve deposits. The fuel-soluble very long chain alkylphenyl polyoxyalkylene amines of the present inv...
The pink color content often produced in products such as amine salts, amine oxides, betaines, quaternary ammonium compounds or other compounds derived from long chain alkyl amines is eliminated by treating the products with trace amounts of a bleaching agent. Heating of the treated amine at ...
petroleum sulfonatesilicates-collector interactionThis study concerns the interaction between residual amine (tallow amine acetate) and sodium oleate for floating mica and metal-oxides respectively from a feldspar ore of Cine-Milas region of Turkey. Zeta-potential measurements show the co-adsorption of ...
