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.4-formylmorpholineBasic Information:Chinese name: N-FormylmorpholineSynonyms: 4-formylmorpholine; N-formylmorpholine; 4-morpholine formaldehyde; N-formylmorpholine; N-formylmorpholine; N-formylmorpholine; N-formylmorpholine; 4-formylmorpholineChinese name N-formylmorpholineForeign name N-FormylmorpholAlias 4-morpholine formaldehydeMolecular formula C5H9NO2CAS: 4394-85-8EINECS: 224-518-3Molecular weight: 115.1305Physical and chemical properties:N-formylmorpholine propertiesMelting point: 20-23 °C(lit.)Boiling point: 236-237 °C(lit.)Density: 1.145 g/mL at 25 °C(lit.)Vapor pressure: 0.03 hPa (20 °C)Refractive index: n20/D 1.485(lit.)Flash point: >230 °FStorage conditions: 2-8°CSolubility: SOLUBLEForm: LiquidColor: Clear yellowPH value: 10 (250g/l, H2O, 20℃)Explosive limit 1.2-8.2%(V)Water solubility: SOLUBLESensitivity: HygroscopicBRN: 110293CAS: database 4394-85-8 (CAS DataBase Reference)NIST Chemical Substance Information: N-Formylmorpholine (4394-85-8)EPA Chemical Substance Information 4-Morpholinecarboxaldehyde (4394-85-8)use:It is used for the desulfurization of natural gas, syngas, flue gas, natural gas condensate and gasoline, etc. It is the extraction solvent of petroleum aromatic hydrocarbon device, and aromatic hydrocarbon can be recovered by extractive distillation. It has good selectivity, good thermal stability and chemical stability. , No poison, no corrosion. It is widely used in the recovery of aromatic hydrocarbon solvents. It is an excellent aprotic solvent with high solubility and selectivity for aromatics. The mixture has been successfully used in aromatics extraction process and butenes concentration process.Storage and transportation:Should be sealed and stored in a dry, cool and ventilated warehousepackage:200KG/drum Storage: It is recommended to store in a dry and cool area with proper ventilation. After the original packaging, please fasten the packaging cover as soon as possible to prevent the water and other substances from mixing into the product and affecting its performance. Store in a cool, dry place, keep the container sealed and avoid contact with oxides. Do not breathe dust, avoid skin and mucous membrane contact. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes. Store contaminated clothing separately and wash it before reuse. Maintain good hygiene habits.
