Title: COPPER-CONTAINING AROMATIC MANNICH COMPLEXES AND CONCENTRATES AND DIESEL FUELS CONTAINING SAME Abstract of the Disclosure This invention relates to copper-containing aromatic Mannich complexes, and to concentrates and diesel fuels containing said complexes. The diesel fuels are useful with diesel engines equipped with exhaust system particulate traps. The copper-containing aromatic Mannich complex is used for lowering the ignition temperature of exhaust particles collected in the trap. The copper-containing aromatic Mannich complex is made by contacting either component (A) or component(B) with component (C); component (A) being at least one compound represented by the formula Image wherein R1 is an allyl group of 1 to about 6 carbon atoms, and R2 is a saturated or unsaturated aliphatic hydrocarbyl group of about 16 to about 20 carbon atoms; component (B) being a mixture of (B)(I) and (B)(II), component (B)(I) being at least one compound represented by the formula Image wherein R3 is an alkyl group of about 9 to about 18 carbon atoms, R4 is an alkylene group of 1 to about 4 carbon atoms, and R5 is a saturated or unsaturated aliphatic hydrocarbyl group of about 16 to about 20 carbon atoms; and component (B)(II) being at least one compound represented by the formula Image wherein R6 and R8 are independently alkyl groups of about 9 to about 18 carbon atoms, and R7 is an alkylene group of 1 to about 4 carbon atoms; and component (C) is at least one copper reactant.
