Inhalation Risk:A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20 °C.
Effects of Short Term Exposure:The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema. The substance may cause effects on the central nervous system, kidneys and liver. Exposure far above the OEL could cause death. The effects may be delayed.
Effects of Long Term Exposure:Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. This substance is possibly carcinogenic to humans. May cause heritable genetic damage to human germ cells.
Description Ethyleneimine is a colourless liquid with an ammonia-like smell or pungent odour. It is highly flammable and reacts with a wide variety of materials. Ethyleneimine is used in polymerisation products, as a monomer for polyethyleneimine and as a comonomer for polymers, for example, with ethylenediamine. Polymerised ethyleneimine is used in paper, textile chemicals, adhesive binders, petroleum, refining chemicals, fuels, lubricants, coating resins, varnishes, lacquers, agricultural chemicals, cosmetics, ion-exchange resins, photographic chemicals, colloid flocculants, and surfactants. Ethyleneimine readily polymerises, and it behaves like a secondary amine. Ethyleneimine is highly caustic, attacking materials such as cork, rubber, many plastics, metals, and glass except those without carbonate or borax. It polymerises explosively on contact with silver, aluminium, or acid. The activity of ethyleneimine is similar to that of nitrogen and sulphur mustards. Ethyleneimine is used as an intermediate in the production of triethylenemelamine.
Physical properties Clear, colorless, very flammable liquid with a very strong ammonia odor. Odor threshold concentration is 1.5 ppm (quoted, Amoore and Hautala, 1983).
Uses Ethylenimine is used in the manufacture oftriethylenemelamine and other amines. Ethyleneimine is used to manufacture triethylenemelamine and is used in its polymeric form in paper and textile chemicals, adhesive binders, petroleum-refining chemicals, fuels and lubricants, coating resins, varnishes, lacquers, agricultural chemicals, cosmetics, ion-exchange resins, photographic chemicals, colloid flocculants, and surfactants. In the manufacture of triethylenemelamine.
