Triethylenetetramine (TETA and trien), also known as trientine when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2. The pure free base is a colorless oily liquid, but, like many amines , older samples assume a yellowish color due to impurities resulting from air oxidation .
Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental ...
In a few cases, tren serves as a tridentate ligand with one of the primary amine groups non-coordinated. Tren is a common impurity in the more common triethylenetetramine ("trien"). As a trifunctional amine, tren forms a triisocyanate when derivatized with COCl 2. TREN is known to react fast in the presence of (aromatic) aldehydes to form an ...

Diethylenetriamine (abbreviated Dien or DETA) and also known as 2,2’-Iminodi(ethylamine) [2]) is an organic compound with the formula HN(CH 2 CH 2 NH 2) 2.This colourless hygroscopic liquid is soluble in water and polar organic solvents, but not simple hydrocarbons.
Near 0 °Bé would be approximately the density of water. −100 °Bé (specific gravity, 0.615) would be among the lightest fluids known, such as liquid butane. Thus, the system could be understood as representing a practical spectrum of the density of liquids between −100 and 100, with values near 0 being the approximate density of water.
PMDTA is used to modify the reactivity of organolithium compounds, which deaggregate in the presence of Lewis bases to enhance their reactivity. [3] Commonly, the ditertiary amine TMEDA is used in these applications; it binds to the lithium center as a bidentate ligand.
These include ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, other higher homologues and aminoethyl piperazine. [ 2 ] [ 3 ] AEP is also manufactured by reacting ethylenediamine or ethanolamine / ammonia mixtures over a catalyst .
