ABSTRACT:
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 presence as the reaction medium of a normally gaseous material which (a) has a critical temperature <160.degree. C. and a critical pressure <12 MPa, (b) is in a liquefied, densified, or supercritical state in which it has a density of at least 0.1 g/cc, and (c) is present in an amount sufficient to maintain the reaction mixture stirrable throughout the reaction.
