N-Ethylmorpholine Chemical Properties,Usage,Production
Chemical Properties
4-Ethylmorpholine is a colorless liquid with an ammonia-like odor.
Physical properties
Colorless, flammable liquid with an ammonia-like odor. Experimentally determined detection and recognition odor threshold concentrations were 400 μg/m3 (85 ppbv) and 1.2 mg/m3 (250 ppbv), respectively (Hellman and Small, 1974).
Uses
Catalyst in polyurethane foam production
Uses
N-Ethylmorpholine is a component of the buffer used in basic peptide separation through anion-exchange chromatography. Further, it acts as a catalyst in the preparation of polyurethane foam.
Uses
Intermediate for dyestuffs, pharmaceuticals; rubber accelerators and emulsifying agents; solvent for dyes, resins, oils; catalyst in making polyurethane foams.
Preparation
N-Ethylmorpholine is synthesized by the reaction of morpholine with bromoethane.

General Description
N-Ethylmorpholine appears as a colorless liquid with a strong ammonia-like odor. Severely irritates skin, eyes, and mucous membranes. Moderately soluble in water and less dense than water. Flash point 83°F.
Air & Water Reactions
Highly flammable. Moderately soluble in water .
Reactivity Profile
N-Ethylmorpholine can react vigorously with oxidizing materials. N-Ethylmorpholine dissolves LiAlH4.
Hazard
Irritant to skin and eyes, absorbed by skin. Flammable, moderate fire risk. Toxic by skin absorption.
Health Hazard
Exposure can cause irritation of eyes, nose and throat. Contact with eyes may result in foggy vision and seeing halos around lights.
Flammability and Explosibility
Flammable
Safety Profile
oison by intravenous route. Moderately toxic by ingestion. Mildly toxic by inhalation. A skin and severe eye irritant. A very dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidzing materials. To fight fire, use alcohol foam, foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx.
Potential Exposure
Primary irritant (without allergic reaction). This material is used as a catalyst in polyurethane foam production. It is a solvent for dyes and resins. It is used as an intermediate in surfactant, dye, pharmaceutical, and rubber chemical manufacture
Environmental Fate
Chemical/Physical. Releases toxic nitrogen oxides when heated to decomposition (Sax and
Lewis, 1987).
At an influent concentration of 1,000 mg/L, treatment with GAC resulted in an effluent
concentration of 467 mg/L. The adsorbability of the carbon used was 107 mg/g carbon (Guisti et
al., 1974).
Shipping
UN2920 Corrosive liquids, flammable, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, 3-Flammable liquid. UN1993 Flammable liquids, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required
Incompatibilities
May form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine,etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Corrodes some metals. Unless inhibited, violent polymerization can occur from heat, sunlight, and contact with strong oxidizers permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Attacks some plastics, rubber and coatings
Waste Disposal
Controlled incineration (oxides of nitrogen are removed from the effluent gas by scrubbers and/or thermal devices).
