Process for the preparation of amine oxides

摘要

A process for the preparation of high quality amine oxides by reacting a tertiary or secondary amine with hydrogen peroxide as an oxidant in the presence of a recyclable heterogeneous layered double hydroxide exchanged with one of the anions of transition metal oxides as a catalyst in an organic solvent at a temperature ranging between 10-25° C. for a period of 1-6 hours under continuous stirring and separating the product by simple filtration and subsequently evaporation of solvents by known methods.
