    Features & Benefits

    Product Highlights

    Ethyleneamines:
    (TETA) are used to aid in the separation of nickel ores from iron sulfide minerals, particularly pyrrhotite and is added as and aqueous solution to ores in the flotation step. The amine depresses the iron sulfide during flotation and allows the separation of nickel ores.

    Safety & Health

    Toxicity and Safety
    • Because of the fragility of eye tissue, almost any eye contact with any ethyleneamine may cause irreparable damage, even blindness.
    • A single, short exposure to ethyleneamines, may cause severe skin burns, whilea single, prolonged exposure may result in the material being absorbed through the skin in harmful amounts.
    • Exposures has caused allergic skin reactions in some individuals. Single dose oral toxicity of ethyleneamines is low. The oral LD50 for rats is in the range of 1000 to 4500 mg/kg for the ethyleneamines.
    • The principal hazards that arise in working with tetraethylenepentamine (TEPA) are those associated with similar organic amines; namely, a corrosive action on skin and eyes.
    • Precautions should be taken to prevent contact with these parts of the body such as by use of protective clothing and chemical goggles. If contact occurs, immediately flush the exposed area with plenty of water for at least 15 minutes. Eye exposures should be examined by a physician.
    • Contaminated clothing should be laundered before reuse. If ingestion occurs, do not induce vomiting. Have the individual drink a large amount of water and transport them to a medical facility immediately.

    Storage & Handling Information

    Dry Inert Gas Blanket
    This product should be stored under a dry inert gas blanket, such as nitrogen, to minimize contamination resulting from contact with air and water.

     

    Storage Temperature
    Tetraethylenepentamine (TEPA) has a pour point of -30°C. To avoid freezing, the product should be maintained above this temperature.

    Spills or Leaks

    • Small spills should be covered with inorganic absorbents and disposed of properly.
    • Organic absorbents have been known to ignite when contaminated with amines in closed containers.
    • Certain cellulosic materials used for spill cleanup such as wood chips or sawdust have shown reactivity with ethyleneamines and should be avoided.
    • Large spills should be contained and recovered. Water may be used for clean-up purposes, but avoid disposing of the material into sewers or natural water bodies. Disposal should be in accordance with all federal, state and local laws, regulations, and ordinances.
    • Ethyleneamine leaks will frequently be identified by the odor (ammoniacal) or by the formation of a white, solid, waxy substance (amine carbamates). Inorganic absorbents or water may be used to clean up the amine waste.
