ANALYTICAL METHOD USING NBSA REAGENT FOR QUANTIFICATION OF PURE AND PHARMACEUTICAL ANTIHISTAMINE DRUGS
A quick and convenient method has been developed for the micro estimation of antihistamine drugs. 1-5 mg of sample is allowed to react with 10 ml of 0.02 M, N-bromosaccharin solution. Unconsumed reagent can be accurately titrated with 5 ml…
DESIGN AND CHARACTERIZATION OF ARDHM CATALYSTS FOR ATMOSPHERIC RESIDUE HYDRODEMETALIZATION IN CRUDE OIL PROCESSING
Synthesis and characterization of atmospheric residue hydrodemetalization (ARDHM) catalyst for crude oil processing have been carried out. The catalyst was synthesized by loading of small amount of Ni and Mo metals onto the Indonesian natural zeolite from Klaten (ZA sample).…
EFFECT OF SURFACTANT MICELLES ON THE REACTIVITY OF PEROXY ANIONS TOWARD BIS (4-CHLORO-3, 5-DIMETHYLPHENYL) PHOSPHATE
The rate enhancement depends on the hydrophobicity of the nucleophile. The micellar catalyzed reaction between bis-4-chloro-3,5-dimethylphenylphosphate ester and hydroxide or hydroperoxide anions has been examined in buffered medium (pH 8-10). First order rate constant (Kψ) for the reaction of hydroxide…
