Abstract

Aqueous solutions of N-methylmorpholine N-oxide having color numbers below 200 APHA, based on an N-methylmorpholine N-oxide content of 50% by weight, are produced by reacting aqueous hydrogen peroxide solutions with aqueous solutions of N-methylmorpholine having a water content of at least 35% by weight.
