N-formylmorpholine (NFM) is an important organic solvent and fine chemical raw material. It is colorless and transparent liquid at room temperature. It has the chemical property of amide, and its aqueous solution can be easily hydrolyzed into morpholine and formic acid under the condition of acid or alkali, and the aqueous solution is weakly alkaline.

N-formyl morpholine is an excellent extraction solvent for the production of aromatic hydrocarbons, and is widely used in synthetic fibers and other fields.
