Products Description
N-Formylmorpholine (NFM) is an essential organic solvent and high-value fine-chemical raw material. At ambient temperature, it is a colorless, transparent liquid with typical amide-related chemical behaviors. Its aqueous solution is weakly alkaline, and it can be easily hydrolyzed into morpholine and formic acid under acidic or alkaline environments.
NFM is acknowledged as a superior extractant for the preparation and separation of aromatic hydrocarbons. It also finds extensive use in synthetic fiber production and numerous other industrial sectors.

Product Application
N-Formylmorpholine (NFM) serves as a vital organic solvent and fine-chemical feedstock. It is a colorless, clear liquid under ambient temperature and displays the characteristic chemical behaviors of amides. Its aqueous solution is weakly alkaline, and the compound readily undergoes hydrolysis to yield morpholine and formic acid in acidic or alkaline surroundings.
As a high-performance extractant for the isolation and purification of aromatic hydrocarbons, N-formylmorpholine is extensively employed in synthetic fiber production and a broad spectrum of other industrial processes.
