Tetraethylenepentamine (TEPA)

Mixture of four different TEPA ethyleneamines and additional higher molecular weight products. These compounds include:TEPA CAS #000112-57-2, N- (2-aminoethyl)-N'-{2- (2-aminoethyl)amino}ethyl}-1,2-ethanediamine
AETETA CAS #031295-46-2, 4- (2-aminoethyl)-N- (2-aminoethyl)-N'-{2- {(2-aminoethyl)amino}ethyl}-1,2-ethanediamine
APEEDA CAS #031295-54-2, 1- (2-aminoethyl)-4-[(2-aminoethyl)-amino]ethyl]-piperazine
PEDETA CAS #031295-49-5, 1-[2-[[2-[(2-aminoethyl)amino]ethyl]-amino]ethyl]-piperazine Polyethylenepolyamines CAS #029320-38-5 or CAS #068131-73-7

Aminat Tetraethylenepentamine (TEPA) can be used in applications including:

• 

  Asphalt Additivess

  Amidoamines, made by reacting ethyleneamines with fatty acids, are used in a number of applications, including asphalt additives to improve properties of paved surfaces.

• 

  Chelating agents

  Polyaminocarboxylic acids and their salts derived from ethyleneamines are used in a variety of applications where specific metal ions interfere with processing, or require buffering, concentrating, separating, or transporting.

• 

  Corrosion Inhibitors

  Amidoamines and substituted imidazolines, prepared by the reaction of DETA or TETA with fatty acids, find use as corrosion inhibitors in petroleum production operations.

• 

  Lube Oil and Fuel Additives

  A major use of ethyleneamines is in the manufacturing of lubricant and fuel additives. Ashless dispersants are used in engine oils to reduce sludge and varnish deposits caused by the low-speed of motor vehicles.

• 

  Mineral Processing Aids

  Amidoamines, made from fatty acids and ethyleneamines, have been used in the processing of minerals.

• 

  Textile Additives

  Uses include applications for man-made and natural fibers and fabrics. Ethyleneamines provide improvements to the properties of dye sorption, adhesion, flame proofing, abrasion resistance, anti-static, and handle.

• 

  Urethane Chemicals

  Ethyleneamines are used in the manufacture of polyols and also in the production of catalysts to react polyols with isocyanates. The main applications of these polyols are in urethane systems for appliances, spray foams, building panels and elastomers.

• 

  Drainage Aids

  Flocculants and drainage aids are used to optimize the separation of a solid phase from the liquid phase in aqueous suspensions. Addition of ethyleneamine-based products drastically increase the rate of particle sedimentation so that a clear, supernatant liquid is obtained.

• 

  Epoxy Curing Agents

  Ethyleneamines are widely used for curing (cross-linking) epoxy resins both as the pure amine or, more often, as a derivative that contains primary and secondary amines which can react with the epoxy resin functionality.

• 

  Fabric Softeners

  Fabric softeners are used to impart softness and antistatic properties to machine washed laundry. These products can be introduced as part of the detergent package, added in the washing machine rinse cycle, or added in the clothes dryer.

• 

  Surfactants

  Amphoteric surfactants are mild surfactants used in shampoos that are active over a wide pH range.

• 

  Wet strength resins

  Applications for wet-strength resins include paper towels, weather resistant packaging, milk cartons, frozen food packages and vegetable boxes. Products requiring immersion in water such as photographic paper, filter paper and certain textiles in hospital bed sheets and gowns are areas where wet strength is important.
