ABSTRACT:
Metal complexes of hydroxyl- and/or thiol-containing Mannich are prepared by reacting a transition metal-containing agent with an aromatic Mannich. The Mannich is prepared from a substituted hydroxyl- and/or thiol-containing aromatic, an aldehyde or ketone, and a hydroxyl- and/or thiol-containing amine compound. A Schiff base is then reacted therewith. The products are useful in reducing soot ignition temperatures in diesel particulate traps.
