Abstract Two molecules, each including tris-2-amino-ethyleneamine (tren), have been produced using a Schiff’s base condensation and long-chain, aliphatic aldehydes. The syntheses are straightforward and can be run in air at ambient temperature. The ability of these molecules to complex with metal ions makes them good candidates for water remediation. The ability of these ligands to hold metal ions in 0.03 M non-aqueous solutions was unexpected. Their syntheses and characterization are discussed.

Amide surfactants have modified structures with lipophilic groups connecting hydrophilic groups through amido bond. The preparation of three families of amide surfactants including long chain N-acyl sarcosinates, amidopropyl dimethyl hydroxypropyl sulfobetaines and lauryl amidopropyl trimethyl ammoniums were discussed. The study of the surface activity of these compounds by measuring the equilibrium surface tensions of their dilute aqueous solutions were described. The minimum surface tension and the critical micelle concentration values of these compounds are given.
