US Patent:

52796272, Jan 18, 1994

Filed:

Nov 6, 1992

Appl. No.:

7/973135

Inventors:

Nai Z. Huang - Mayfield Hts. OH
Christopher J. Kolp - Euclid OH
Christopher R. Sgarlata - Cleveland OH

Assignee:

The Lubrizol Corporation - Cleveland OH

International Classification:

C10L 500
C07F 108

US Classification:

44367

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); component (A) being at least one compound represented by the formula ##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.
