ABSTRACT:
A non-aromatic tert-amine is oxidized with hydrogen peroxide at about 20.degree.-100.degree. C. by a carbon dioxide-accelerated high solids process in which discoloration of the amine oxide product is minimized by diluting the carbon dioxide before allowing it to contact the reaction mixture so that the entire reaction is conducted in an atmosphere composed of carbon dioxide and an amount of inert gas, such as nitrogen or air, which is at least equal in volume to the amount of carbon dioxide.
