Overview:
N-formylmorpholine (NFM) is an important organic solvent and fine chemical raw material. It is a colorless transparent liquid at room temperature. It has the chemical properties of amide, and its aqueous solution is easily hydrolyzed into morpholine and formic acid in the presence of acid or alkali, and the aqueous solution is weakly alkaline.
N-formylmorpholine is an excellent extraction solvent for aromatics, and is widely used in synthetic fibers and other fields.
