We must activate aluminum in oil shale residue before its removal, that is to convert inactive hexacoordinate aluminum in the residue into the active quadridentate
or five-coordinate aluminum in order to become an acid-soluble material for leaching.
The Schiff base ligand is acting as quadridentate dianionic chelating agent and produces symmetric square planar complexes with metal ions like Co (II), Ni (II), Cu (II), and Zn (II).
The ligand was found to be acting as quadridentate dianionic ligand.
The Gibb's free energy of activation has positive value showing the stable quadridentate nature of ligand surrounding the metal center.
