Overview:
Triethylene diamine, also known as triethylenediamine. White or light yellow crystals. Ammonia flavor, this product is an organic synthesis intermediate, synthetic light stabilizing material, widely used in polyurethane foam, elastomer and plastic products and molding process. Or polymer initiator, can be used as ethylene polymerization catalyst and epoxy-ethane polymerization catalyst, its derivatives can be used as corrosion inhibitors, emulsifiers and so on.
Basic information:
Short for: TEDA, DABCO,PC CAT TD100
English name: TRIETHYLENEDIAMINE
Chemical formula: C6H12N2
Physicochemical properties
TEDA is normally colorless or white crystal, which is easy to absorb moisture and caking when exposed to air, is alkaline, and can absorb CO2 in the air and turn yellow. It is easily soluble in acetone, benzene and ethanol. Pure TEDA is very toxic, inhaling saturated TEDA vapor will cause minor mucosal irritation, eye damage, irritation of the skin will cause allergies.
Relative density (25 ° C) : about 1.14
Melting point of pure product: 158-159℃
Flash point: 60℃
Boiling point: 174℃, easy to sublimate, slightly ammonia flavor
Steam pressure: about 67Pa at 21℃, 533Pa at 50℃, 7.7kPa at 100℃
Preparation:
There are several methods to synthesize TEDA at home and abroad. The general process is to put the aqueous solution of amine or alcohol amine raw material through the reactor filled with catalytic zeolite at a certain flow rate, react at 320-400℃, 0.3MPa under the condition of purification, to obtain TEMA.
Disclosure treatment
Stop leaks as much as possible while ensuring safety. If a minor leak is found, treat it with sand or other absorbent material and place it in a clean, dry container for subsequent treatment. If a large amount of leakage occurs, the leaked material should be collected for subsequent treatment. Avoid material entering groundwater or surface water, because it is not easily degraded by biological matter. All collected leakage materials should be disposed of in accordance with the relevant regulations of the local environmental protection department.
