4-Ethylmorpholine is a colorless liquid with
an ammonia-like odor.
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).
Catalyst in polyurethane foam production
Intermediate for dyestuffs, pharmaceuticals;
rubber accelerators and emulsifying agents; solvent for dyes, resins, oils; catalyst in making
polyurethane foams.
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.
N-Ethylmorpholine is synthesized by the reaction of morpholine with bromoethane.
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.
Highly flammable. Moderately soluble in water .
N-Ethylmorpholine can react vigorously with oxidizing materials. N-Ethylmorpholine dissolves LiAlH4.
Irritant to skin and eyes, absorbed by
skin. Flammable, moderate fire risk. Toxic by skin
absorption.
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
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.
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
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).

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
Controlled incineration (oxides of nitrogen are removed from the effluent gas by scrubbers and/or thermal devices).
