Definitions

  • the invention relates to fuels for gasoline engines with small amounts of amides from aminoalkylene polycarboxylic acids and secondary long-chain amines.
  • Carburetor and intake system of gasoline engines are increasingly contaminated by contaminants caused by dust particles from the air, unburned hydrocarbon residues from the combustion chamber and the crankcase ventilation gases that are led into the carburetor.
  • the first generation of additives could only prevent the formation of deposits in the intake system, but not remove existing deposits again, whereas the modern additives of the second generation can do both ("keep-clean” and “clean-up effect") and indeed, due to changed thermal properties, in particular also at zones of higher temperatures, namely at the inlet valves.
  • the molecular construction principle of fuel detergents can be generalized as a combination of polar structures with mostly higher molecular, non-polar or lipophilic residues.
  • A is a straight-chain or branched alkylene radical having 2 to 6 carbon atoms or the rest of the formula R essentially denotes straight-chain aliphatic radicals, in particular alkyl radicals having 10 to 30, preferably 14 to 24, carbon atoms, the amide structures also partially or completely in the form of the ammonium salt structure of the formula may be present, is particularly effective in relation to carburetor and valve pitch.
  • the amides or amide ammonium salts or ammonium salts e.g. nitrilotriacetic acid, ethylenediaminetetraacetic acid or propylene-1,2-diaminetetraacetic acid are obtained by reacting the acids with 0.5 to 1.5 mol amine, preferably 0.8 to 1.2 mol amine per carboxyl group.
  • reaction temperatures are about 80 to 200 ° C, with the amides being continuously removed from the water of reaction formed. However, the reaction does not have to be carried out completely to give the amide; rather, 0 to 100 mol% of the amine used can be present in the form of the ammonium salt.
  • Dialkylamines are particularly suitable in which R is a straight-chain alkyl radical having 10 to 30 carbon atoms, preferably 14 to 24 carbon atoms.
  • Dioleylamine, dipalmitinamine, dicoconut fatty amine and dibehenylamine and preferably ditallow fatty amine may be mentioned in particular.
  • the amides or ammonium salts of the aminoalkylene polycarboxylic acids of the formulas I and II to be used according to the invention are added to the fuels in amounts of 50 to 1000 ppm, preferably 100 to 500 ppm.
  • Leaded and unleaded regular and premium gasoline can be used as fuels for gasoline engines.
  • the gasolines can also contain components other than hydrocarbons, e.g. Alcohols such as methanol, ethanol, tert-butanol and ethers, e.g. Contain methyl tertiary butyl ether.
  • the fuels generally also contain further additives such as corrosion inhibitors, stabilizers, antioxidants and / or detergents.
  • Corrosion inhibitors are mostly ammonium salts org. Carboxylic acids which tend to form films due to the structure of the starting compounds. Amines to lower the pH are also often found in corrosion inhibitors. Heterocyclic aromatics are mostly used as non-ferrous metal corrosion protection.
  • amines such as para-phenylenediamine, dicyclohexylamine, morpholine or derivatives of these amines are antioxidants or stabilizers call.
  • Phenolic antioxidants such as 2,4-di-tert-butylphenol or 3,5-di-tert-butyl-4-hydroxiphenylpropionic acid and their derivatives are also added to fuels and lubricants.
  • Amides and imides of polyisobutylene succinic anhydride, polybutene polyamines and long-chain carbonamides and imides are also optionally contained in the fuels as further carburetor, injector and valve detergents.
