COPPER-CONTAINING ORGANOMETALLIC COMPLEXES AND CONCENTRATES AND DIESEL FUELS CONTAINING SAME

摘要

The present invention relates to copper-containing organometallic complexes, and concentrates and diesel fuels containing the complexes. Diesel fuel is useful for diesel engines equipped with exhaust particulate traps. Copper-containing organometallic complexes are used to lower the dropping temperature of the exhaust particles collected in the trap. Copper-containing organometallic complexes can form complexes with (i) organic compounds that are dissolved or stably dispersed in diesel fuel and contain (i) at least two functional groups attached to hydrocarbon bonds, and (ii) organic compounds (i). Derived from copper-containing metal reactants. The functional group Wherein X is 0 or S, R is H or hydrocarbyl, R ^* is hydrocarbylene or hydrocarbylidene and a is a number (eg, from 0 to about 10). Copper may be combined with one or more metals selected from the group consisting of Na, K, Mg, Ca, Sr, Ba, V, Cr, Mo, Fe, Co, Zn, B, Pb, Sb, Ti, Mn and Zr. . The present invention also relates to a method for operating a diesel engine in which the exhaust device particulate traps which depend on the diesel fuel described above are autonomous.
