AMINE C-6

This product is obtained as a coproduct from commercial continuous operation. It is a clear, dark amber liquid composed primarily of a mixture of aliphatic and heterocyclic mono- and diamines. The dominant heterocyclic group present is the morpholinyl ring, and the oxyethylene linkage appears frequently in the various compounds present. This product is completely miscible with water.

    Safety & Health

    Toxicity and Safety
    • The acute oral LD50 of Amine C-6 is approximately 8.75 g/kg and the product is considered, therefore, to be practically nontoxic by swallowing in single doses.
    • The undiluted product appears to penetrate skin readily, since the LD50, by single 24-hour skin contact to rabbits is about 3.85 g/kg.
    • Nevertheless, the latter figure indicates only a moderate to slight degree of hazard insofar as actual absorption through the skin is concerned.
    • Skin irritation to rabbits is slight at the lowest dosage and increases in severity with increasingly higher dosages.
    • Undiluted Amine C-6 is very irritating to eyes. As with other caustic materials, dilution with water would be expected to reduce this hazard. In case of eye contact, the eye should be irrigated continuously with water for at least 15 minutes.
    • A physician should see all cases in which undiluted Amine C-6 has splashed into the eye.
    • All spills of Amine C-6 on the skin should be washed off promptly with soap and water. If clothing has become saturated, it should be removed at once, and affected skin areas washed thoroughly with soap and water.
    • Such measures will aid in preventing immediate irritant effects as well as the development of skin sensitivity that may occur in susceptible persons from prolonged contact or repeated exposure.
    • Vapor concentrations of Amine C-6 that are likely to develop under ordinary working conditions would constitute little immediate hazard to health. Acutely dangerous exposures might be expected to occur only after massive spills in closely confined areas.
    • Although no threshold limit for Amine C-6 vapor has been established, the breathing of high concentrations should be avoided. A chemical cartridge respirator or gas mask, offering protection against organic vapor, should be worn when entering vessels for purposes of cleaning or maintenance unless thoroughly flushed with water beforehand.
    • It has been observed that certain individuals exposed to vapor of aliphatic amines may complain of hazy vision as from a film over the eye. This symptom may develop at vapor concentrations that cause no obvious discomfort.
    • It is said to result from a mild degree of corneal edema, and disappears without residual injury several hours after discontinuance of exposure. This is reported to occur after exposure to a number of amines and must be regarded as a sign of overexposure.
    • Amine C-6 should be handled only in well-ventilated areas. Wherever practical, process equipment should be provided with exhaust ventilation to prevent buildup of vapor concentrations in the workroom atmosphere. 
    • Maintenance personnel at work on equipment that has contained Amine C-6 should wear the above listed protective equipment.

    Storage & Handling

    Storage and Handling Conditions
    • Carbon steel is a satisfactory material for storing and handling Amine C-6.
    • Copper, zinc, lead, or alloys containing any of these materials should not be used since they will be attacked by the product.
    • The freezing point will vary over a wide range. Since it can freeze as high as 50°C, it will be necessary to provide heat to the storage tank.
    • Generally, this can be done by utilizing either internal or external heating coils of a suitable area to heat the tank contents.
    • If these coils are internal, they should be built into the tank about six inches above the floor and operated on low-pressure steam.
    • The coils should be constructed in such a manner as to allow the condensate to drain.Mild steel is acceptable for transfer lines.
    • Since the product will leach conventional pipe dopes from threaded connections, the lines should be welded or flanged.
    • Satisfactory gasketing materials are Garlock 7021, U.S. Rubber 899, John Crane 333, Johns- Manville 70, or equivalent.
    • Centrifugal pumps constructed out of carbon steel or black iron are satisfactory. Either pump packing or a mechanical seal may be used.
    • Braided Teflon or polypropylene is satisfactory packing materials. Seals may be John Crane Type 9, Durametallic Type RO-TT, or equivalent with either stellite and carbon or tungsten faces and Teflon V-rings.
