Ru(III)-Catalyzed Oxidative Cleavage of Ritodrine Hydrochloride: A Kinetic and Mechanistic Study
Abstract: A systematic kinetic and mechanistic study of the oxidation of ritodrine hydrochloride (RTH) with chloramine-T (CAT) in both HClO4 and NaOH media has been carried out at 303 K. In acid medium, the reaction rate is very sluggish to be measured kinetically. Ruthenium (III) chloride ([Ru(III)]) was found to be an efficient catalyst. The reaction rate exhibits a first-order dependence on [CAT]0 in both media. It shows a fractional-order on …

Aluminum and its Alloys to Recover from Corrosive Weather
Abstract: Corrosion is defined as deterioration of material, usually metal, because of reaction with its environment and which requires presence of an anode, a cathode, an electrolyte and an electrical circuit. Aluminum and its alloys are reactive to weather of exposure, e.g. ambient, acid and alkalis. Solid to pigments are prevented from corrosion by using inhibitors. Organic inhibitors are ever praised due to non-toxic performances. Basic processes are surface adsorption to …
