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 .
The pK a of protonated triethylamine is 10.75, [4] and it can be used to prepare buffer solutions at that pH. The hydrochloride salt, triethylamine hydrochloride (triethylammonium chloride), is a colorless, odorless, and hygroscopic powder, which decomposes when heated to 261 °C. Triethylamine is soluble in water to the extent of 112.4 g/L at ...
Liquid water has a density of approximately 1 g/cm 3 (1 g/mL). Thus 100 mL of water is equal to approximately 100 g. Therefore, a solution with 1 g of solute dissolved in final volume of 100 mL aqueous solution may also be considered 1% m/m (1 g solute in 99 g water). This approximation breaks down as the solute concentration is increased (for ...
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.
Sometimes specific volume is expressed in terms of the number of cubic centimeters occupied by one gram of a substance. In this case, the unit is the centimeter cubed per gram (cm 3 /g or cm 3 ·g −1). To convert m 3 /kg to cm 3 /g, multiply by 1000; conversely, multiply by 0.001. Specific volume is inversely proportional to density.
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 imine. During this process, water is formed, making it a condensation reaction.
Oleylamine reacts with carboxylic acid to form its carboxylate salt through an exothermic reaction. [8] [9] Its carboxylate salt can further condensate into amides through the loss of one water molecule. In the presence of acetic acid, oleylamin forms with DNA insoluble complexes with the radii of the particles equal 60–65 nm. [10]
Normality is defined as the number of gram or mole equivalents of solute present in one liter of solution.The SI unit of normality is equivalents per liter (Eq/L). = where N is normality, m sol is the mass of solute in grams, EW sol is the equivalent weight of solute, and V soln is the volume of the entire solution in liters.
