ملخص المقالة :

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 solvents have been studied. The solvent effect was analyzed usingKamlet-Taft's and Swain's multiparametric equations. Finally, a mechanism consistent with theobserved results has been proposed and discussed.
