Metal complexes of Schiff base with a Mannich Bases

摘要

The present Invention relates to metal complexes of Mannich Bases containing hydroxyl and / or thiol reacting Agent containing transition metal with an Aromatic Mannich base.The Mannich is prepared from an Aromatic thiol containing hydroxyl and / or replaced, an aldehyde or ketone and Amine Compound containing hydroxyl and / or thiol.Can be optionally REACT a Schiff base, the products are useful to reduce Ignition temperature of Soot in Diesel Particulate traps.
