n-ethylmorpholine

N-Ethylmorpholine (CAS 100-74-3), abbreviated NEM, is a tertiary amine used as a catalyst and pH-regulating agent in specialty chemical manufacturing.

Where is n-ethylmorpholine used?

• Reactive intermediate and process catalyst
• Solvent where controlled basicity and miscibility with polar media are required
• Polyurethane: blowing and gelation catalyst influencing foam cell structure in flexible and rigid foam formulations
• Coatings and resins: neutralizing amine that stabilizes waterborne systems and adjusts pH in acrylic and alkyd dispersions
• Pharmaceutical synthesis: non-nucleophilic base and reaction solvent in multi-step organic processes
• Metalworking fluids and lubricant concentrates: corrosion inhibitor component and emulsion stabilizer
• Mild basicity makes it suitable for sensitive chemical reactions.

Commercial specifications

• Purity commonly 99% or above for process-critical uses
• Specifications vary by supplier
