Effect of temperature on the viscosity of cationic micellar solutions in the presence of added salts
(1987)
The effect of temperature on the viscosities of cetyltrimethylammonium salts (CTA X, X =Br-, NO3-, Tosylate) in the presence of added salts is presented. It was found that plots of 1n of relative viscosity vs 1/T was linear ...
Behavior of low-solubility detergents
(1992)
The solubility behavior in water of different salts of cetyltrimethyl ammonium (CTA+), such as iodide (CTAI), thiocyanate (CTASCN), and perchlorate (CTAClO4), is reported. The order of solubilities is CTASCN > CTAI > ...
Metal tetrazole complexes: bis-(5-aminotetrazolato)-copper (II)
(1960)
Two crystalline forms of bis-(5-aminotetrazolato)-copper (II) have been prepared and characterized. Visible and ultraviolet spectra of aqueous copper (II)-5-aminotetrazole solution have been examined. Continuous variation ...
Electrolyte effects on the cationic micelle catalyzed decarboxylation of 6-nitrobenzisoxazole-3-carboxylate anion
(1973)
The unimolecular decarboxylation of 6-nitrobenzisoxazole-3-carboxylate ion is strongly catalyzed by micelles of cationic and nonionic surfactants. The catalysis by cationic micelles can be enhanced by adding some electrolytes ...
Micellar Effects upon Phosphorylation and Phosphate Ester Hydrolysis
(1969)
The reactions between hydroxide or fluoride ion and p-nitrophenyl diphenyl phosphate, catalyzed by micelles of cetyltrimethylammonium bromide, are inhibited by phenyl, diphenyl, and p-t-butylphenyl phosphate. With decreasing ...
Solvent effects on electrophilicity
(American Chemical Society, 2001)
Continuum solvent effect on the electrophilicity index recently proposed by Parr and co-workers (Parr, R. G.; von Szentpaly, L.; Liu, S. J. Am. Chem. Soc. 1999, 121, 1922) is discussed in detail. Solvent effect is introduced ...
Woodward-Hoffmann rule in the light of the principles of maximum hardness and minimum polarizability: DFT and Ab initio SCF studies
(2000)
Electrocyclic transformation between cis-butadiene and cyclobutene has been studied at the HF and DFT levels with 6-311G** basis sets. The disrotatory stationary point with two imaginary vibrational frequencies is associated ...
Polysoap Solutions: Air-Water Interfacial Properties
(1993)
Four sodium polysoaps from poly[malcic anbydride-co-styrene] were synthesized and the surface properties of their aqueous solutions at the air-water interface were determined. The surface tension lowering was directly ...
Self-assembly of catalytically active colloidal molecules: tailoring activity through surface chemistry

Temperature Dependence of the Photochemistry of Aryl Alkyl Ketones
(1983)
The photochemistry of several phenyl alkyl and p-anisyl alkyl ketones has been examined using laser flash photolysis and conventional quantum yield techniques. The methoxy-substituted ketones show higher activation energies ...
