Kinetics and mechanism of quinolinium dichromate mediated oxidation of sugar alcohols in Bronsted acid media

Bronsted acid catalyzed oxidation of certain sugar alcohols (polyols) has been studied by quinolinium dichromate (QDC) using aqueous sulfuric, perchloric, and hydrochloric acids at different temperatures. At constant acidity, reaction kinetics revealed the second-order kinetics with a first order in [Alcohol] and [QDC]. Zucker-Hammett, Bunnett, and Bunnett-Olsen criteria were used to analyze acid-dependent rate accelerations. Bunnett-Olsen plots of (log k + Hν) versus (Hν + log [H+]), and (log k) versus (Hν + log [H+]) afforded slope values (? and ?*, respectively)?>?0.47, suggesting that a water molecule acts as a prton transfer agent in the slow step of the mechanism in the oxidation of alcohols by QDC in the presence of aqueous sulfuric, perchloric, and hydrochloric acids.

Kinetics and mechanism of oxidation of arsenic(III) by quinolinium dichromate(QDC) in aqueous perchloric acid

The kinetics of oxidation of arsenic(III) by quinolinium dichromate(QDC) has been investigated spectrophotometrically over a wide range of arsenic(III) concentrations in aqueous perchloric acid medium and at a constant ionic strength. As the arsenic(III) concentration varies, from lower concentration region to higher one, the order with respect to [arsenic(III)] changes from first to zero order. In all the regions of the [arsenic(III)], the reaction is first order in [oxidant] and less than unit order in [acid]. Increase in [perchloric acid] accelerates the reaction rate. The added products, chromium(III) and arsenic(V) do not significantly affect the reaction rate. A suitable mechanism is proposed and the involved reaction constants have been evaluated. Activation parameters have also been calculated.
