摘要： The invention relates to a process for producing a solution of N-methyl morpholine-N-oxide in water, in which (a) an aqueous solution is used which contains N-methyl morpholine and morpholine and has a pH between 6.0 and 9.0, whereafter (b) said aqueous solution is treated with a peroxidic oxidising agent in order to oxidise N-morpholine to N-methyl morpholine-N-oxide.
