Description

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. <BR>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. <BR>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.
