Oxyhalogen-sulfur chemistry: Kinetics and mechanism of oxidation of n-acetylthiourea by aqueous bromate and acidified bromate

Oxyhalogen-sulfur chemistry: kinetics and mechanism of oxidation of N-acetylthiourea by chlorite and chlorine dioxide.

The oxidation reactions of N-acetylthiourea (ACTU) by chlorite and chlorine dioxide were studied in slightly acidic media. The ACTU-ClO(2)(-) reaction has a complex dependence on acid with acid catalysis in pH > 2 followed by acid retardation in higher acid conditions. In excess chlorite conditions the reaction is characterized by a very short induction period followed by a sudden and rapid for...

Kinetics and mechanism of oxidation of D-mannitol by potassium bromate in aqueous acidic medium

Kinetic investigation in Rh(III) catalyzed oxidation of D-Mannitol in an acidified solution of potassium bromate in the presence of Hg(OAc)2 as a scavenger, have been studied in the temperature range of 30 45 C. Increase in concentration of oxidant and H ion showed fractional positive order and fractional inverse order respectively. The influence of Hg(OAc)2, ionic strength and Cl ion on the ra...

Kinetics and Mechanism of Aquachlororuthenium (III) Catalyzed Oxidation of Tartaric Acid by Acid Bromate

The kinetics of the oxidation of Ru (III) catalyzed oxidation of tartaric acid by potassium bromate in aqueous perchloric acid medium at constant ionic strength was investigated in the temperature range 303318 K. The reactions exhibit first order kinetics at low concentration of bromate, tending to zero order at high concentration. Zero order kinetics with respect to [tartaric acid] and first o...
