METAL COMPLEXES OF MANNICH BASES

摘要

Title: METAL COMPLEXES OF MANNICH BASES Metal complexes of hydroxyl and/or thiol containing Mannichs 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 can optionally be reacted therewith. The products are useful in reducing soot ignition temperatures in diesel particulate traps. BACKGROUND The present invention relates to metal reaction products of Mannich type compounds which generally do not degrade fuels and yet reduce the ignition temperature of soot as in a diesel particulate trap.
