Kinetic and Mechanistic Study of Oxidation of Piperazines by Bromamine-T in Acidic Medium

Oxidations of piperazine, 1-methylpiperazine and 1-ethylpiperazine by bromamine-T (BAT) in buffered acidic medium have been kinetically studied at 303 K. The reaction shows a first-order dependence of the rate each on [BAT]0 and [piperazine]0, and an inverse fractional-order dependence on [H]. The additions of halide ions and the reduction product of BAT, p-toluenesulfonamide, have no effect on...

KINETICS OF OXIDATION OF AMITRIPTYLINE BY BROMAMINE-B AND BROMAMINE-T IN ACIDIC BUFFER (pH 1.2) MEDIUM

Kinetic, mechanistic and thermodynamic investigations on Iridium (III) catalyzed oxidation of D-Mannitol by N-chloro-p-toluenesulfonamide in perchloric acid medium

The present paper deals with the kinetics and mechanism of homogeneously Ir(III) chloride catalyzed oxidation of D-mannitol by chloramine-T [CAT] in perchloric acid medium in the temperature range of 30 to 45 0C. The reaction is carried out in the presence of mercuric acetate as a scavenger for chloride ion. The experimental results show first order kinetics with respect to the oxidant [CAT] an...

Kinetics of Oxidation of Indigo Carmine by N-Sodio-N- Bromotoluenesulfonamide in Acidic Buffer Medium

The kinetics of oxidation of indigo carmine (IC) by N-sodio-N-bromotoluenesulfonamide or bromamine-T (BAT) in pH 5 buffer medium has been investigated at 30°C using spectrophotometry at 610 nm. The reaction rate shows dependencies of first-order on [IC] 0 , second-order on [BAT]0, fractional order on [H 1], and inverse first-order on [p-toluenesulfonamide]. The addition of chloride and bromide ...

Kinetic and Mechanistic Study of Oxidation of Diethylamine by N-Sodio-N- Bromobenzene Sulphonamide (Bromamine-B) in Acid Solution: Catalyzed by Ru(III)

Kinetics of oxidation of diethylamine (DEA) by Bromamine-B (BAB) has been investigated at in acid solution with Ru(III) as catalyst. The oxidation behavior obeys 303 K the rate law, rate 5 k [BAB] [DEA] [Ru(III)] [H1]2x where ‘x’ is less than unity indicating retardation of rate by [H]. Added halide ions, the reaction product benzenesulphonamide, variation of ionic strength and dielectric const...
