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...
متن کاملKinetics and thermodynamics of the esterification reaction according to the Langmuir-Hinshelwood mechanism
In this work, kinetics and thermodynamics of esterification reaction were studied. This research investigated the esterification reaction between methanol and acidified oil catalyzed by sulfonated cation exchange resin and proposed a new rate equation for consideration of kinetics of this reaction according to the Langmuir-Hinshelwood mechanism. Thermodynamics and kinetics parameters were calcu...

متن کاملMechanism of the dihydroorotase reaction.
Dihydroorotase (DHO) is a zinc metalloenzyme that functions in the pathway for the biosynthesis of pyrimidine nucleotides by catalyzing the reversible interconversion of carbamoyl aspartate and dihydroorotate. A chemical mechanism was proposed on the basis of an analysis of the effects of pH, metal substitution, solvent isotope effects, mutant proteins, and alternative substrates on the enzyme-...
متن کاملMechanism of the Aldolase Reaction.
Upon treatment with carboxypeptidase, muscle aldolase (ketose-l-phosphate aldehyde-lyase, EC 4.1.2.7) loses 3 COOHterminal tyrosine residues (3, 4) and exhibits a 20-fold fall in the rate of fructose diphosphate cleavage (3) and a 500-fold fall in the rate of exchange detritiation of dihydroxyacetone phosphate (5). The cleavage of fructose-l-P is relatively unchanged (3). The present investigat...
