Abstract

Gegenstand der Erfindung ist ein Verfahren zur Verbesserung der Kaltfließeigenschaften von Ölen mit einem Schwefelgehalt von weniger als 500 ppm und einem Gehalt an n-Paraffinen der Kettenlänge C18 und länger von mindestens 8 Gew.-%, gekennzeichnet durch die Zugabe eines Additivs, enthaltend eine Mischung aus

  • A) 15 bis 50 Gew.-% eines Copolymers, enthaltend neben 87 bis 92 mol-% von Struktureinheiten, die sich von Ethylen ableiten;
  • a) 6,5 bis 12 mol-% Struktureinheiten, die sich von Vinylacetat ableiten,
  • b) 0,5 bis 6 mol-% Struktureinheiten, die sich von 4-Methylpenten-1 ableiten,
    mit der Maßgabe, daß die Summe der molaren Anteile der Struktureinheiten a) und b) 8 bis 14 mol-% beträgt,
    • und
  • B) 85 bis 50 Gew.-% mindestens eines weiteren Copolymers oder Terpolymers aus Ethylen und Vinylestern oder Acrylsäureestern, das für sich allein ein Kaltfließverbesserer ist.
    • Weitere Gegenstände der Erfindung sind ein Additiv zur Verbesserung der Kaltfließeigenschaften von Mineralölen und Mineralöldestillaten sowie Brennstoffölzusammensetzungen, die diese Additive umfassen.The invention relates to a process for improving the cold flow properties of oils with a sulfur content of less than 500 ppm and a content of n-paraffins of chain length C 18 and longer of at least 8% by weight, characterized by the addition of an additive containing one Mixture of
  • A) 15 to 50% by weight of a copolymer containing, in addition to 87 to 92 mol% of structural units which are derived from ethylene;
  • a) 6.5 to 12 mol% of structural units which are derived from vinyl acetate,
  • b) 0.5 to 6 mol% of structural units which are derived from 4-methylpentene-1,
    with the proviso that the sum of the molar proportions of the structural units a) and b) is 8 to 14 mol%,
    • and
  • B) 85 to 50% by weight of at least one further copolymer or terpolymer composed of ethylene and vinyl esters or acrylic acid esters, which is a cold flow improver in itself.
    • Other objects of the invention are an additive to improve the cold flow properties of mineral oils and mineral oil distillates and fuel oil compositions comprising these additives.
