摘要： A simplified process for preparation of an alkenylsuccinimide or a polyalkenylsuccinimide is described, characterized in that it comprises successively: a stage (a) in which an alkenylsuccinic anhydride or a polyalkenylsuccinic anhydride is prepared by bringing about an ene-synthesis reaction between at least one olefin or one polyolefin and at least one unsaturated dicarboxylic anhydride that is selected from maleic anhydride and the maleic anhydrides that are substituted by 1 or 2 methyl groups, characterized in that said reaction is carried out within at least one aromatic solvent that is selected from toluene and the xylenes that are used at a ratio of between 30 to 70% by weight of the reaction mixture and in which a fraction of said unsaturated dicarboxylic anhydride does not react with said olefin or polyolefin; a stage (b) in which the product of stage (a) that contains unsaturated, unreacted dicarboxylic anhydride is reacted with at least one alcohol or an amine; and a stage (c) in which the product that is obtained in stage (b) is reacted with an amine. These succinimides can be used as detergent additives for engine fuels and as ashless dispersing additives for engine lubricants.

摘要： A new laboratory test for evaluating the tendency of a gasoline, which may contain additives, to produce deposits during running of an engine involves the following steps: a tube is placed in the injector oven of a gas chromatograph; said tube is kept at a constant temperature in a constant flow of air; the gasoline or additive-containing gasoline to be evaluated is injected through said tube; and the quantity of deposits formed is determined by weighing said tube after dismantling.
