Formulations of nitrogenated additives for engine fuels and the engine fuels containing them |
摘要 |
Formulations of additives for engine fuels comprising at least one constituent (A) and one constituent (B) resulting from the reaction of at least one alkenyl or polyalkenyl-succinic derivative with at least one polyamine to form constituent (A) and with at least one 1-(2-hydroethyl) imidazoline substituted in the 2-position by a linear or branched alkyl or alkenyl radical with 1 to 25 atoms of carbon to form constituent (B). The preferred formulations also contain a constituent (C) consisting of at least one polyglycol soluble in said fuel, with an average molecular mass ranging from 480 to 2,100. The (A)/(B) and (A)+(B)/(C) molar ratios preferably are respectively 0.2/1 to 5/1 and 0.05/1 and 20/1.
