Abstract
The sodium perborate oxidation of morpholine and N-methylmorpholine is firs t order In the oxidant and substrates, occurs at pH 8.4-10.5 but proceeds i n 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 mecha nism is discussed and a rate law is derived.
