Kinetics and Mechanism of Oxidation of Thiocyanate Ion by Sodium N-Chloro-4-methyl Benzene Sulphonamide in Alkaline Medium
Thiocyanate Ion, Chloramine-T Kinetics of oxidation of potassium thiocyanate by the oxidant chloramine-T (CAT) in presence of NaOH has been studied at 30 °C. At low substrate concentrations, the approximate rate law is, — d[CAT]/dt = k[CAT][KNCS]/[NaOH]2. At higher substrate concentrations, the rate law simplifies to, —d[CAT]/dt = k[CAT]/[NaOH]. Ionic strength and addition of p-toluene sulphona...
متن کاملThe Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics
The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...
متن کاملKinetics and Mechanism of Oxidation of n-Pentanol by Tetramethylammonium Fluorochromate
The oxidation of n-pentanol by tetramethylammonium fluorochromate in acidic solution wasstudied using spectrophotometric technique. The reaction was arranged to be under pseudo firstorderconditions respect to the oxidant. A Michaelis-Menten type kinetic was observed respect tothe substrate. The reaction is catalyzed by hydrogen ions. Dependences of the reaction rates ontemperature and different...
متن کاملOxidation of Gabapentin by Potassium Ferrate (VI) in Alkaline Media-Kinetics and Mechanism Study
In the present research, the reaction kinetics of Potassium Ferrate (VI) with gabapentin were studied by using spectrophotometer. The reaction was determined under alkaline condition at the different temperatures of 288.2K-308.2K. All data was obtained from the pseudo-first order reaction. It was found that the reaction is a first-order for reactant. The observed rates constants (kobs) increase...
متن کاملKinetics and mechanism of oxidation of semicarbazide by Keggin type 12-tungstocobaltate(III) in acidic medium
The kinetics of oxidation of semicarbazide by 12-tungstocobaltate (III) in aquous acidic medium at 300K and a constant ionic strength of 0.3 mol dm was studied spectrophotometrically at λmax 624nm under pseudo first-order conditions. The reaction between semicarbazide and 12-tungstocobaltate (III) in acidic medium exhibits 1:2 stiochiometry [Semicarbazide:12-tungstocobaltate (III)]. The main ox...
