<span style="font-family:Arial,Helvallergic reaction. Ethylamine has low oral toxicity in a single dose. The dose of ethylethylamine for oral LD50 in rats is between 1000~4500mg/kg. use triethylenetetramine (TETA) The main hazards arising are those associated with similar organic amines; ie corrosive effects on skin and eyes. Precautions should be taken to prevent contact with these parts of the body, such as the use of protective clothing and chemical goggles. If contact occurs, immediately flush exposed area with copious amounts of water for at least 15 minutes. Eye exposure should be checked by a physician. Contaminated clothing should be washed before reuse. If ingestion occurs, do not induce vomiting. Have individual drink plenty of water (or milk, if available) and get to a medical facility right away. Toxicity and safe handling of this product For more information, please refer to the Material Safety Data Sheet (European Safety Data Sheet) before using this product.
Handling and Storage In order to keep triethylenetetramine (TETA ) of high purity for manufacture and transport, the following storage and handling considerations are recommended:
Dry Inert Gas Pack This product should be stored in a dry inert Under a blanket of gas, such as nitrogen, to minimize contamination from contact with air and water.
Construction materials Slight coloring with ethylamine is ok Accepted, storage tanks may be made of carbon steel or black iron, provided they are free of rust and galling. However, if the amine is stored in such tanks, color may develop due to iron contamination. If iron contamination cannot be tolerated, tanks constructed of 304 or 316 stainless steel should be used. (Note: Do not use copper, copper alloys, brass, or bronze in tanks or lines as they are rapidly corroded by amines.) The recommended storage structure for TETA is stainless steel.
Storage temperature Triethylenetetramine (TETA) The pouring point is -35.1°C. To avoid freezing, the product should be kept above this temperature.
Leaks Small spills should be covered with inorganic absorbers agent and handle it properly. Organic absorbents are known to ignite when contaminated with amines in closed containers. Certain cellulosic materials used for spill cleanup, such as wood chips or sawdust, have been shown to react with ethylamine and should be avoided. should be controlled and recycled. Water may be used for clean-up purposes, but release of material into sewers or natural bodies of water should be avoided. Disposal should comply with all federal, state and local laws, rules and regulations. Ethylamine leaks are usually identified by an odor (ammonia) or the formation of a white solid waxy substance (amine carbamate). Amine wastes can be removed using inorganic absorbents or water.
Availability Triethylenetetramine (TETA) can Available in bulk and in 55 gallon drums with a net weight of 200kg.
