Abstract
The sodium perborate oxidation of morpholine and N-methylmorpholine is first order in the oxidant and substrates, occurs at pH 8.4–10.5 but proceeds in neither acidic nor alkaline solution. Perborate oxidation is faster than hydrogen peroxide oxidation. Also, the presence of boric acid enhances both types of oxidations. The kinetic results indicate that peroxoborate anion acts as oxidizing species along with hydrogen peroxide. The oxidation mechanism is discussed and a rate law is derived.
