  2. Triethylenetetramine - Wikipedia

    en.wikipedia.org/wiki/Triethylenetetramine

    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 .

  3. Toxicity characteristic leaching procedure - Wikipedia

    en.wikipedia.org/wiki/Toxicity_characteristic...

    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 ...

  4. Amine value - Wikipedia

    en.wikipedia.org/wiki/Amine_value

    It is the number of Nitrogens x 56.1 (Mwt of KOH) x 1000 (convert to milligrams) divided by molecular mass of the amine functional compound. So using Tetraethylenepentamine (TEPA) as an example: Mwt = 189, number of nitrogen atoms = 5 So 5 x 1000 x 56.1/189 = 1484. So the Amine Value of TEPA = 1484

  6. Tris(2-aminoethyl)amine - Wikipedia

    en.wikipedia.org/wiki/Tris(2-aminoethyl)amine

    Tris(2-aminoethyl)amine is the organic compound with the formula N(CH 2 CH 2 NH 2) 3.This colourless liquid is soluble in water and is highly basic, consisting of a tertiary amine center and three pendant primary amine groups.

  7. Mass concentration (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Mass_concentration_(chemistry)

    In water solutions containing relatively small quantities of dissolved solute (as in biology), such figures may be "percentivized" by multiplying by 100 a ratio of grams solute per mL solution. The result is given as "mass/volume percentage". Such a convention expresses mass concentration of 1 gram of solute in 100 mL of solution, as "1 m/v %".

  8. Diethylenetriamine - Wikipedia

    en.wikipedia.org/wiki/Diethylenetriamine

    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.

  9. PMDTA - Wikipedia

    en.wikipedia.org/wiki/PMDTA

    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.
