Definitions

  • the invention relates to fuels for gasoline engines which contain small amounts of a mixture of a detergent and a mono- or dialkoxylated polyisobutylamine.
  • 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 additive generation could only prevent the formation of deposits in the intake system, but not remove existing deposits in the intake system, 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 high temperatures, namely at the inlet valves.
  • a detergent component in the mixture with the dispersant according to the invention it is possible in principle to use any known product suitable for this purpose, such as those e.g. with J. Falbe, U. Hasserodt, catalysts, surfactants and mineral oil additives, G. Thieme Verlag Stuttgart 1978, p. 221 f. or in K. Owen, Gasoline and Diesel Fuel Additives, John Wiley & Sons 1989, pp. 23 ff.
  • Polyisobutylamines according to EP 0 244 616, ethylenediamine acetic acid amides and / or imides according to EP 0 188 786 or polyether amines according to EP 0 356 725 are preferably used, reference being made to the definitions in these references. Due to the manufacturing process, the products described there have the additional advantage of being almost free of chlorine or chloride.
  • the detergents mentioned usually show excellent effectiveness in valve and carburetor cleanliness, but, as already mentioned above, are at best neutral, i.e. without an adverse effect on an engine lubricant, so show no positive effect with regard to a desired sludge dispersion.
  • fuels for gasoline engines are, in addition to (A) the detergents mentioned (B), polyisobutylamine derivatives in small amounts, preferably in amounts of 50 to 2000 ppm, of the formula I. added, in which R is a polyisobutyl radical with a molecular weight of 500 to 5000, R1 is hydrogen, methyl or ethyl and m and n independently of one another are the numbers 0 or 1.
  • the ratio of (A) to (B) is usually 1: 2 to 10: 1.
  • polyisobutylamines preferably obtained by hydroformylation and subsequent reductive amination of reactive polyisobutenes according to EP-A2-0 244 616, to which reference is hereby made, are reacted with alkylene oxides in a manner known per se.
  • the polyisobutene used has a molecular weight between 500 and 5000, preferably between 800 and 1500. It is obtained according to a known method by cationic polymerization of isobutene, with a reactive double bond remaining in the monomer last incorporated after termination of the polymer chain, which is used for the purpose of further functionalization can be.
  • the mono- or dialkoxylation is carried out by reacting the amine with alkylene oxides, preferably with ethylene oxide, in a manner known per se, e.g. in the presence of a certain proportion of water in a pressure vessel, the amine is reacted with the approx. 1 to 5 times molar amount of alkylene oxide, e.g. at S.P. McManus et al., Synth. Commun. 3, 177 (1973). Depending on the choice of the amount of alkoxide, mono- or dialkoxylated amines are obtained.
  • the alkoxylation products of the formula I in addition to their known valve cleaning action, have a particularly positive effect on the sludge-carrying capacity of weakly or not at all additive engine oils, particularly when ethylene oxide is used as the alkylene oxide.
  • 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 ether, e.g. Contain methyl tertiary butyl ether.
  • the fuels generally also contain additives such as corrosion inhibitors, stabilizers, antioxidants and / or other 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. Rating Engine part Basic value Add 125 ppm polyisobutylamine + 125 ppm ethoxylated polyisobutylamine Add 250 ppm of non-ethoxylated polyisobutylamine Cylinder head cover 8.7 9.2 8.9 Oil distribution pipe 8.3 9.3 8.5 Cylinder head 8.3 9.5 8.5 Oil pan 8.2 9.5 8.9 Timing case cover 8.5 9.6 8.6 Average 8.4 9.4 8.7
  • the table shows the advantageous effect of the polyisobutyl ethoxylate to be used according to the invention compared to the starting polyisobutylamine.
  • the dispersing properties of the ethoxylate make it possible to raise the mean value from the rating of the individual engine parts from 8.4 to 9.4 (max. 10).
  • the use of polyisobutylamine does not lead to an improvement compared to the basic value.
