Kinetics of oxidation of acetylsalicylic acid ( Aspirin ) by manganese ( III ) in pyrophosphate medium
Manganese( III) has been stabili zed in weakly acidic med ium by means of pyrophosphate and the nature of the complex elucidated spectrophotometricall y. Stoichiometry of manganese( JJJ) oxidation of aspirin (acetylsalicylic acid) in pyrophosphate has been establi shed in the pH range 2.3-3.5 by iodometric and spectrophotometric methods. The reac ti on foll ows first order kinetics in [Mn(IIl)j...
متن کاملComparative Study of Kinetics of Catalyzed Oxidation of D (+)galactose and lactose by Ruthenium (III) in Alkaline Medium
Kinetic investigation in Ru(III) catalyzed oxidation of D(+)-galactose and lactose in an alkaline solution of potassium bromate in the presence of mercuric acetate as a scavenger for Br – ion has been carried out in the temperature range 30-45°C. The rate shows first order dependence with respect to the bromate and zeroth order with respect to the substrate (sugars). The reaction exhibits first...
متن کاملKinetic, 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...
متن کاملKinetics of oxidation of chloroprocaine hydrochloride by N-halo-p-toluene sulfonamides in acid medium: A Mechanistic approach
A kinetic study of oxidation of a potent local anaesthetic chloroprocaine hydrochloride by sodium Nhalo-p-toluenesulfonamides (chloramine-T and bromamine-T) has been carried in HClO4 medium at 303 K. The rate shows a first-order dependence on both [oxidant]o, and [substrate]o, and a fractional-order dependence on acid concentration. Increase in the rate of reaction has been observed with decrea...
متن کاملMechanistic studies of uncatalyzed and ruthenium(III)-catalyzed oxidation of the antibiotic drug chloramphenicol by hexacyanoferrate(III) in aqueous alkaline medium: a comparative kinetic study
ABSTRACT The kinetics of oxidation of the antibiotic drug chloramphenicol (CHP) by hexacyanoferrate(III) (HCF) has been investigated spectrophotometrically both in the absence and presence of ruthenium(III) catalyst in aqueous alkaline medium at 25 °C and at constant ionic strength of 1.10 mol dm-3. The stoichiometry is identical in both cases, i.e. [CHP]/[HCF] = 1:2. The oxidation products wer...
