    摘要: A material having a use as a detergent in a motor fuel composition is the reaction product of an aldehyde, a phenoxy acid, and a mono- or diamine, wherein the aldehyde includes a hydrocarbon radical having from 1 to about 10 carbon atoms and the phenoxy acid has the following formula: ##STR1## wherein R is any hydrocarbon radical or oxygen-containing hydrocarbon radical of from 1 to about 36 carbon atoms with the carbon atom adjacent to the carboxylic acid functional group having at least one active hydrogen atom, and x varies from about 1 to 3. The monoamine useful in forming the reaction product has the formula: ##STR2## wherein X, X.sup.1 and X.sup.2 can be any hydrocarbon radical having from about 6 to about 36 carbon atoms, and wherein X.sup.1 and X.sup.2 can be a hydrogen atom. The diamine has the formula: ##STR3## wherein z varies from about 1 to 3, R.sup.1 is any hydrocarbon radical or oxygen substituted hydrocarbon radical having from about 6 to 36 carbon atoms and R.sup.2 is a hydrogen or a methyl group.

    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.
