  • Copper-containing aromatic mannich complexes and concentrates and diesel fuels containing same
    Patent number: 5348559
    Abstract: 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); ##STR1## wherein R.sup.1 is an alkyl group of 1 to about 6 carbon atoms, and R.sup.2 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 ##STR2## wherein R.sup.3 is an alkyl group of about 9 to about 18 carbon atoms, R.sup.4 is an alkylene group of 1 to about 4 carbon atoms, and R.sup.
