BENZENE-1 2-DIOL MANNICH BASES, LIGANDS, POLYMERS, AND SELECTIVE METAL ION REMOVAL METHOD |
| abstract |
A complexing ligand for forming a complex with a cation, the ligand comprising an aromatic component including two or more attachment sites for the cation, an optionally substituted amine, such as an aminoalkylene group, and a hydrocarbon chain of from 1 to 12 carbon atoms in length. The amine component of the ligand is capable of taking on an internal counterion (H+) so that the complex of the target cation and ligand has an overall neutral charge. Such ligands can be used to extract a target cation or cations from an aqueous solution. This has particular application for the separation of aluminium and silicon in aqueous liqors in a Bayer process. The ligand can be a simple compound formed by the Mannich condensation of catechol with formaldehyde and an amine. The ligand may alternatively be a bis-ligand, a polymer or an ion exchange resin. A range of new compounds and intermediates are also described. |
