Physical and chemical properties

Aliphatic nitrogen tetramines such as tris(2-aminoethyl)amine can be used in research and industrial fields such as chelating agents, corrosion inhibitors, resin curing agents, catalysts, and organic intermediates. Its outstanding structural feature is that there are 4 N atoms with strong coordination ability in the molecule, which can form stable chelates with a bicyclic structure with most metal ions.

resolve resolution

In a 2000 ml glass reactor, 120.5 g of nickel hydroxide and 146.2 g of tris(2-aminoethyl)amine were added to 2000 ml of H2O. The solution was stirred at 50°C for 8.5 hours. Excess nickel hydroxide was removed by centrifugation (30 min, 4400 rpm). The solution was recovered by decantation to obtain the title compound tris(2-aminoethyl)amine. The exact concentration of nickel was determined using inductively coupled plasma coupled optical emission spectroscopy (ICP-OES). The synthesis route is shown in the figure.
