    摘要: Amine salts of orthophosphoric acid or its ester, when dissolved in unleaded gasoline in an effective amount, reduce the erosion of non-hardened exhaust valve seats in automotive engines operating on said gasoline. The preferred salts are the amine salts of branched chain primary alkyl acid esters of orthophosphoric acid.

    摘要: Diesel fuel composition comprising a mixture of hydrocarbons boiling in a range from about 310.degree. to 475.degree. F. containing an additive mixture composed of (1) dimeric and trimeric acids produced by the condensation of unsaturated aliphatic monocarboxylic acids having between about 16 and about 18 carbon atoms per molecule, and hydroxyaliphatic monocarboxylic acids having between about 16 and about 18 carbon atoms per molecule, (2) a normally liquid completely or partially neutral amine salt of an oxo-alkyl acid ester of orthophosphoric acid in which each esterifying oxo-alkyl group contains 13 to 16 carbon atoms and the amine is an aliphatic hydrocarbon monoamine of 16 to 24 carbon atoms in which each aliphatic hydrocarbon radical is attached to the nitrogen through a saturated carbon atom, (3) an aliphatic demulsifier consisting of fatty acids alkoxylated by a mixture of ethylene and propylene oxides and (4) a saturated hydrocarbon solvent.
