Induction Model for the Heterogeneously-Catalyzed Liquid-Phase Oxidation of Aldehydes

Abstract

The effects of heptaldehyde concentration and inert surface on the induction period were investigated in the system of the heterogeneously-catalyzed liquid-phase oxidation of aldehydes. A theoretical model was developed, which provided a more complete insight into the induction phenomena of the heterogeneously-catalyzed liquid-phase oxidation of aldehydes. Experimental results of induction time correlated well with the theoretical induction model.

The Role of Water in Lanthanide-Catalyzed Carbon–Carbon Bond Formation

“…An example of the resulting data is plotted in Figure 5 , which exemplifies the linear increase of product concentration as a function of time for the conditions studied between 18 and 66 min. By monitoring the linear increase in product, 3 , concentration as a function of time we were able to calculate the steady state reaction rates as the slope of the best fit line in Figure 5 [ 21 ]. Table 2 contains a complete list of steady state reaction rates.…”

Enhanced acyl radical formation in the Au nanoparticle-catalysed aldehydeoxidation

“…This suggests that termination can be controlled by the walls of the reaction vessel. 13 A related phenomenon was observed when ZnO-supported gold catalyst (Au/ZnO) 14 was used. The oxidation in the presence of this catalyst was partially suppressed.…”
