The Kinetics of Tripropylammonium Fluorochromate Oxidation of Mandelic Acids
The oxidation of Mandelic Acids (MA) to the corresponding oxoacids with tripropylammonium fluorochromate (TriPAFC) in aqueous acetic acid has been studied. The reaction is first order with respect to [TriPAFC], [MA] and [H+]. The oxidation of α-deuteriomandelic acid shows the presence of a primary ki...
متن کاملKinetics and Mechanism of Oxidation of n-Pentanol by Tetramethylammonium Fluorochromate
The oxidation of n-pentanol by tetramethylammonium fluorochromate in acidic solution wasstudied using spectrophotometric technique. The reaction was arranged to be under pseudo firstorderconditions respect to the oxidant. A Michaelis-Menten type kinetic was observed respect tothe substrate. The reaction is catalyzed by hydrogen ions. Dependences of the reaction rates ontemperature and different...

متن کاملKinetics of oxidation of Thiomalic acid by Quinaldinium fluorochromate
The kinetics of oxidation of thiomalic acid by quinaldinium fluorochromate(QnFC) has been studied in non aqueous medium. The oxidation kinetics was followed photoelectric colorimetrically in the temperature range of 30°C–60°C. The reaction shows unit order dependence each with respect to substrate and oxidant. The reaction is catalyzed by hydrogen ions. The hydrogen ion dependence takes in the ...
