Abstract
The initiation reaction of autoxidation of acrylaldehyde with Cobalt (III) acetylacetonate, Co(III) (acac)3, was studied. The rate of initiation reaction was measured using the "DPPH technique". Acrylaldehyde was shown to have a much smaller rate of initiation than propionaldehyde. The rate dependence on the partial pressure of oxygen for autoxidation of acrylaldehyde was discussed by comparing the kinetic data of acrylaldehyde with those of propionaldehyde. Effects of solvents on the initiation reaction were also discussed in detail.
