Trien

Trien is a term that can refer to several different chemical compounds. Most commonly, it is used as an abbreviation for triethylenetetramine, a colorless liquid with the chemical formula C6H18N4. Triethylenetetramine is a polyamine, meaning it contains multiple amine groups. It is a common building block in the synthesis of various organic compounds and is used as a curing agent for epoxy resins, an additive in fuels and lubricants, and in the production of chelating agents.

Another compound that might be referred to as trien is 1,4,7-triazacyclononane, a cyclic triamine with the formula C6H15N3. This compound is known for its ability to coordinate with metal ions, forming stable complexes. It finds applications in coordination chemistry and as a ligand in catalysis.

In some contexts, "trien" could also be a shorthand for certain types of unsaturated organic molecules containing three double bonds. However, without further specification, the interpretation often defaults to triethylenetetramine due to its widespread industrial use. The specific meaning of "trien" is dependent on the context in which it is used.
