Kinetics of the Reaction of 2,6-Di-tert-Butylphenol with Methyl Acrylate in the Presence of Potassium 2,6-Di-tert-Butylphenolate and the Effect of Proton Donor Components on the Reaction Mechanism

摘要

The kinetic scheme of the reaction of 2,6-di-tert-butylphenol (ArOH) with methyl acrylate (MA) in the presence of potassium 2,6-di-tert-butylphenolate (ArOK) is proposed and elementary constants are calculated for the catalytic steps and the influence of proton donor components ArOH, H2O and CH3OH on kinetic regularities is studied. The kinetic scheme contains 30 components and involves 62 rate constants of elementary steps which were computed by the mathematical simulation method of process kinetics using a computer. The comparison was carried out for the computed and experimental data relating to the consumption rate dependence of ArOH on ArOK concentration and the concentration of proton donor components.
