Abstract
The authors synthesized chelate surfactants having hydrophobic alkyl group and hydrophilic metal ion which was bonded to the former in chelate configuration, and investigated their properties.
N-lauroyl ethylenediamine (LEDA) was introduced as hydrophobic chelating agent and salts of some transitional metals (e.g. iron, cobalt, nickel, copper, chromium) were adopted.
The reaction of LEDA with ferric sulfate in 1 : 1 equivalent reaction ratio afforded [Fe (LEDA) (H2O) 4] 3/2 SO4. In other reactions pure chelates were not obtained, but the products showed good surface activities.
