PROCESS FOR PREPARING SOLID AMINE OXIDES

摘要

A solid amine oxide is prepared by reacting a tert-amine with at least a stoichiometric amount of an aqueous hydrogen peroxide having a concentration of at least 50 % by weight in the absence of any organic solvent to supplement the small amount of water contributed by the hydrogen peroxide solution, at least the latter part of the reaction being conducted in an amount of liquefied gas, preferably carbon dioxide, to maintain the reaction mixture stirrable throughout the reaction.
