[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.

Hazard InformationBack Directory
[General Description]

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 .
[Reactivity Profile]

N-ETHYL MORPHOLINE(100-74-3) can react vigorously with oxidizing materials. N-ETHYL MORPHOLINE(100-74-3) dissolves LiAlH4.
[Air & Water Reactions]

Highly flammable. Moderately soluble in water .
[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.
[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
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

[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
[Chemical Properties]

4-Ethylmorpholine is a colorless liquid with an ammonia-like odor.
[Chemical Properties]

colourless liquid
[Waste Disposal]

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

N-Ethylmorpholine is synthesized by the reaction of morpholine with bromoethane.

[Flammability and Explosibility]

Flammable
[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).
