Abstract

Uncatalyzed liquid-phase oxidation of cyclododecene was studied in a batch reactor. Cyclododecene was oxidized with molecular oxygen in the temperature range of 363-383 K. Cyclododecene oxide, cyclododecene hydroperoxide, and cyclododecenol were obtained as reaction products. The oxidation kinetics were studied in detail, and a mechanism was devised based on the experimental results and existing literature. The kinetic data were generated at different reaction parameters and fitted successfully with a rate equation based on autocatalysis by total products. The values of the reaction rate constants and activation energy were determined. A distinct difference was observed between the reaction rates of the cis and trans isomers of cyclododecene. The oxidation kinetics were also studied in a stainless steel reactor to examine the wall catalytic effect. The presence of metal ions was found to affect the product distribution.
