| N-formylmorpholine |
| English name: |
N-formylmorpholine |
| EINECS: |
224-518-3 |
| Alias: |
N-formylmorpholine |
| Chemical formula: |
O((CH2)2)2NCOH |
| Production capacity: |
2000t/year |
| Feature: |
Colorless transparent liquid。Density1.1528g/cm3, Boiling point244℃ Melting point20-21℃ , Flash point124℃. |
| Use: |
N-Formylmorpholine, not only chemically stable, non-toxic and non-corrosive, and because of its unique structure, and aliphatic hydrocarbons, aromatic hydrocarbon and water compatibility, dissolved aromatics, which greatly reduces the relative volatility of the aromatics.
Used in desulfurization and solvent extraction in C4 (LNG) cracking project to increase the yield (relative to DMF, ACN, NMP processes). At present, there is the C4 cracker using N-formylmorpholine as extraction solvent in operation in our country. This product has good application in benzene hydrogenation project and coking benzene refining project. Currently, the use of N-formylmorpholine as extraction agent in this two projects has been very mature. |
