The Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics
The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...

Hydroxy acid, oxidation, bromine The oxidation of glycollic, lactic, a-hydroxybutyric, and 2-phenyllactic acids by aque ous bromine has been studied. The reaction is of first order with respect to the oxidant and the anion of the hydroxy acid respectively. The active oxidising species is molecular bromine. The oxidation of ci,a-dideuterioglycollic acid indicated a kinetic isotope effect, ^h /^...
متن کاملOxidation of Some Aliphatic Aldehydes by Chloramine-t
Kinetic studies on the oxidation of acetaldehyde, propionaldehyde, nand tso-butyraldehyde have been made using diloramine-T as an oxidising agent in an alkaline medium. The reactions followed almost identical kinetics being first order with respect to both aldehyde and chloramine-T. The order with respect to alkali has been found to be almost equal to unity (0.8 to 0.90) . Effect of an increase...
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...
