Kinetics and preparation of amine oxides

Abstract A kinetic model for the oxidation of dimethyllaurylamine to its amine oxide with hydrogen peroxide was developed. It is a second‐order reaction where k=.0250, .0079 and .0037 kg per mol/min at 75, 60 and 50°C, respectively. Amine oxides ofN‐lauryl morpholine, piperidine and 3‐methyl piperidine were synthesized, and their rates of formation were determined. Compared to dimethyllaurylamine, the piperidines react slower, while the morpholine reaction is much faster.
