    摘要: The detergent properties of a motor fuel are improved by incorporating therein a minor amount of a succinimide oxamide prepared by reacting a polyalkyleneamine succinimide with an amount of oxalic acid sufficient to react with at least 30 percent of the reactive nitrogen moieties on the succinimide chain.

    摘要: A process for stabilizing fuels during storage by blending therewith oxalic acid derivatives of mono- or bis-succinimides of polyalkylpolyamines. The fuels are stabilized by the presence of 10 to 100 parts per thousand barrels of these oxamides. For particular applications mixtures of mono- and bis-succinimides in varying proportions can be used.
