Disclosed are fuel compositions including alcohol-extended fuels containing friction-reducing, anti-corrosion and detergent amounts of at least one fuel soluble glycine derivative of the formula:RNHCH.sub.2 Xwherein R is a hydrocarbyl group having 6 to 18 carbons and X is ##STR1## wherein R.sub.1 is lower alkyl having 1 to 5 carbon atoms; R.sub.2 is alkylene having 1 to 5 carbon atoms; R.sub.3 is an alkylamino or alkylpolyamino group having 1 to 5 carbon atoms.
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.

A fuel composition comprising a mixture of hydrocarbons boiling in the middle distillate boiling range and an effective stabilizing amount of a alpha, omega diamino poly(oxypropylene) poly(oxyethylene) poly(oxypropylene) represented by the formula: ##STR1## wherein x and z each has an approximate value ranging from 1 to 3 such that the sum of x plus z has an average value ranging from 3 to 4, and y has an approximate value ranging from 10 to 16.
摘要:
A novel fuel composition contains ethanol or gasohol plus, as a wear-inhibiting additive, a quaternary ammonium reaction product of an amine ##STR1## typically bis(2-hydroxyethyl)cocoamine and a phosphate, or phosphonic acid, typically dilauryl phosphate.
摘要:
Alcohols may be inhibited against corrosion by addition thereto of an ether amine (R-O-R").sub.a -NH.sub.3-a typically C.sub.13 H.sub.27 -0-(CH.sub.2).sub.3 -NH.sub.2.
摘要:
Mixed reaction products of isatoic anhydride and N-alkyl trimethylene diamines are found to be effective carburetor detergents for gasoline. Stoichiometric amounts of the reactants are refluxed in an inert solvent for 2 to 8 hours and filtered off to provide the detergent products.
