75-55-8

A clear colorless liquid with an ammonia-like odor. Flash point 25°F. Toxic by ingestion, inhalation and through skin absorption. Less dense than water. Vapors are heavier than air. Produces toxic oxides of nitrogen during combustion. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. Used as an organic intermediate.

PROPYLENEIMINE, [INHIBITED] is subject to violent polymerization on contact with an acid. (The inhibitor is intended to prevent polymerization). Incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides.

Highly flammable. Soluble in water. Reacts slowly and non hazardously with water to form propanolamine or methylethanolamine.

Flammable, dangerous fire risk. Toxic by ingestion, inhalation, and skin absorption. Upper respiratory tract irritant and kidney damage. Possi- ble carcinogen.

Toxic after acute exposure. Can severely irritate eyes, skin, and lungs.

Propyleneimine is used in the modifi- cation of latex surface coating resins; in the production of polymers for use in the paper and textile industries as coat- ings and adhesives.

Chemical is extremely flammable; vapors are heavier than air. Toxic oxides of nitrogen are produced during combustion. Avoid acids, strong oxidizers. Thermally unstable. Hazardous polymerization may occur. Contact with acid promotes violent polymerization.

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, includ- ing 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 medi- cal attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

UN1921 Propyleneimine, stabilized, Hazard Class: 3; Labels: 3-Flammable liquid, 6.1-Poisonous materials.

Vapors or liquid 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, epoxides, water, carbonyl compounds; quinones, sulfonyl halides. May explode in heat. Subject to violent polymerization in contact with acids. Hydrolyzes in water to form methylethanolamine.

colourless oily fuming liquid

Propyleneimine is a fuming, colorless, oily liquid with a strong ammonia-like odor.

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Controlled incineration (incinerator equipped with a scrubber or thermal unit to reduce nitrogen oxides emissions).

Intermediate in production of polymers, coatings, adhesives, textiles, and paper finishes.

The renal papillary toxin.

ChEBI: 2-Methylaziridine is a member of aziridines.

2-Methylaziridine is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

The initial threshold screening level (ITSL) for 1,2-propylenimine is 5 μg/m3 with an 8-hour averaging time.
