Triethylenetetramine

Triethylenetetramine (often abbreviated as TETA) is a chemical compound with the formula (C2H4NH)2. It is a colorless liquid although commercial samples can appear yellow. It has a strong ammonia-like odor. It is used in the synthesis of chelating agents and polymers.

Chemical Structure

Triethylenetetramine is a polyamine and a diamine. It is a derivative of piperazine. Its four amine groups make it a useful cross-linking agent and chelating agent. The compound is used in the production of certain rubbers and resins, and as a hardener for epoxy resins.

Synthesis

Triethylenetetramine is synthesized from diethylenetriamine via a reaction with acrylonitrile followed by hydrogenation of the resulting dinitrile.

Applications

Triethylenetetramine is used in a variety of applications. It is used as a cross-linking agent in the production of epoxy resins. It is also used in the production of certain types of rubber and resin. In addition, it is used as a chelating agent in the chemical industry, particularly in the mining industry for the extraction of certain types of metals.

Safety

Triethylenetetramine is a strong base and can cause burns if it comes into contact with the skin or eyes. It is also harmful if swallowed or inhaled. Proper safety equipment should be used when handling this chemical.
