Tert-butyl carbazate (1) reacted with ammonium thiocyanate and phenyl isothiocyanate to afford the corresponding 5-tert-butoxy-4H-1, 2, 4-triazole-3-thiol (3) 5-tert-butoxy-4-phenyl-2H1, 2, 4-triazole-3(4H)-thione 5 respectively. Compound (1) also reacted with carbon disulfide and potassium hydroxide to afford 5-tert-butoxy-1, 3, 4-oxadiazole-2(3H)-thione 6. Treatment of 6 with methyl iodide, 2...

Binding studies of cationic detergents such as cetyltrimethyl ammonium bromide, Cetyl pyridinium bromide and dodecyl trimethyl ammonium bromide with β Lactoglobulin were carried out by equilibrium dialysis, ultraviolet difference and circular dichroism techniques at 25 C. Binding isotherms at pH 5·0, 7·0 and 9·0 show cooperative binding at all concentrations of detergents and the number of avai...

rearrangement of propargyl amine salt, in the presence of a base was studied and it was concluded that this occurs through an allenic intermediate.

The photo catalytic oxidation of Surfactant Hexadecyltrimethyl-ammonium bromide in aqueous diluted solution has been investigated. Compressed air was used as oxidant and the temperature was maintained at 25-30°C. Effect of UV rays alone and in combination of hydrogen peroxide (H O ) and titanium 2 2 dioxide (TiO ) on Hexadecyltrimethyl-ammonium bromide (C H NBr) was recorded. Finally, from HPLC...

The use of metal oxide nanomaterials as photocatalysts for wastewater treatment has received significant attention in recent years due to their unique physicochemical properties. In this study, we a polyol-mediated refluxing method synthesize silver-incorporated copper (Ag@CuO NMs). tetra butyl ammonium bromide (TBAB) capping agent and ethylene glycol reducing Ag+ Ag is elaborated upon. prepare...

The proposed work describes the nanodrop spectrophotometric determination of cationic surfactants using citrate-modified silver nanoparticles based on the aggregation of silver nanoparticles induced by cationic surfactants due to the hydrophobic effect. The visible color change in the solution of silver nanoparticle includes a red shift with the quenching of the absorption spectra. The maximum ...
