N-Methylmorpholine is theorganic compound with the formula O(CH₂CH₂)₂NCH₃. It is a colorless liquid. It is a cyclictertiary amine. It is used as a base catalyst for generation ofpolyurethanes and other reactions. It is produced by the reaction ofmethylamine anddiethylene glycol as well as by the hydrogenolysis of N-formylmorpholine.^[2] It is the precursor toN-methylmorpholineN-oxide, a commercially important oxidant.
