Description

Verfahren zur Verbesserung der Filtrierbarkeit und des Stockpunktes von Kohlenwasserstoffmitteldestillaten Es ist bekannt, die Filtrierbarkeit von Gasölen durch Zugabe von Hartparaffinen zu verbessern. Durch diesen Zusatz wird eine mikrokristalline Ausscheidung des Paraffins bewirkt und damit eine bessere Filtrierbarkeit erzielt.Process for improving the filterability and the pour point of hydrocarbon middle distillates It is known the filterability of gas oils to be improved by adding hard paraffins. This addition makes it microcrystalline Causes the paraffin to be eliminated and thus achieves better filterability.

Weiterhin wurde vorgeschlagen, die Filtrierbarkeit und den Stockpunkt von Gasölen durch Zugabe von Kondensationsprodukten aus aromatischen Kohlenwasserstoffen und Chlorparaffinen zu verbessern.Furthermore, the filterability and the pour point have been suggested of gas oils by adding condensation products from aromatic hydrocarbons and chlorinated paraffins to improve.

Auch die Zugabe von polymeren Acryl- oder Methacrylsäureestern zu Gasölen ist bereits bekannt. Überraschenderweise wurde nun gefunden, daß man die Filtrierbarkeit und den Stockpunkt von Kohlenwasserstoffmitteldestillaten, wie leichte Heizöle, Gasöle oder Dieselöle, unter Zusatz von Hartparaffin mit einem Schmelzpunkt oberhalb 50°C, vorteilhaft oberhalb 60°C, verbessern kann, wenn man den Kohlenwasserstoffmitteldestillaten 0,01 bis 0,5 Gewichtsprozent Hartparaffin und 0,01 bis 0,5 Gewichtsprozent eines Mischpolymerisates aus Estern, die eine äthylenische Doppelbindung und überwiegend 8 bis 18, vorzugsweise 12 bis 16 C-Atome in der aliphatischen Kohlenwasserstoffkette enthalten, zusetzt.Also the addition of polymeric acrylic or methacrylic acid esters too Gas oils are already known. Surprisingly, it has now been found that the Filterability and pour point of hydrocarbon middle distillates such as light Heating oils, gas oils or diesel oils, with the addition of hard paraffin with a melting point above 50 ° C, advantageously above 60 ° C, can improve if you use the hydrocarbon middle distillates 0.01 to 0.5 percent by weight hard paraffin and 0.01 to 0.5 percent by weight of one Copolymers of esters that have an ethylenic double bond and predominantly 8 to 18, preferably 12 to 16 carbon atoms in the aliphatic hydrocarbon chain included, adds.

Das Hartparaffin wird in Mengen von 0,01 bis 0,5 Gewichtsprozent, zweckmäßig von 0,05 bis 0,2 Gewichtsprozent, und das genannte Mischpolymerisat in Mengen von 0,01 bis 0,5 Gewichtsprozent, zweckmäßig von 0,05 bis 0,2 Gewichtsprozent, zugesetzt.The hard paraffin is used in amounts of 0.01 to 0.5 percent by weight, expediently from 0.05 to 0.2 percent by weight, and the said copolymer in Amounts from 0.01 to 0.5 percent by weight, expediently from 0.05 to 0.2 percent by weight, added.

Die Verbesserung der genannten Eigenschaften der Mitteldestillate durch die kombinierte Zugabe von Hartparaffin und den genannten Mischpolymerisaten ist wesentlich größer als die Summe der Wirkungen der einzelnen Komponenten.The improvement of the mentioned properties of the middle distillates through the combined addition of hard paraffin and the copolymers mentioned is much greater than the sum of the effects of the individual components.

Die erfindungsgemäß verwendeten Mischpolymerisate werden hergestellt aus Estern, die eine äthylenische Doppelbindung und überwiegend 8 bis 18, vorzugsweise 12 bis 16 C-Atome, in der ahphatischen Kohlenwasserstoffkette enthalten. Geeignete Mischpolymerisate sind z. B. Acrylsäure- und/oder Methacrylsäureester des Stearyl-, Dodecyl- oder 2-Äthylhexylalkohols, Vinylstearat, Vinyllaureat, Vinyloleat, Methyllaurylfumarat, Maleinsäureäthylester, Maleinsäurecetylester und Maleinsäuremyristylester.The copolymers used according to the invention are produced from esters which have an ethylenic double bond and predominantly 8 to 18, preferably 12 to 16 carbon atoms, contained in the ahphatic hydrocarbon chain. Suitable Copolymers are z. B. acrylic and / or methacrylic acid esters of stearyl, Dodecyl or 2-ethylhexyl alcohol, vinyl stearate, vinyl laureate, vinyl oleate, methyl lauryl fumarate, Maleic acid ethyl ester, maleic acid cetyl ester and maleic acid myristyl ester.

Mischpolymerisate, die mehr als 300/, an Seitenketten mit weniger als 8 C-Atomen enthalten, sind in ihrer Wirkung schlechter.Copolymers which contain more than 300 % of side chains with fewer than 8 carbon atoms are less effective.

Für die Herstellung der erfindungsgemäß zu verwendenden Mischpolymerisate wird im Rahmen der Erfindung kein Schutz beansprucht.For the production of the copolymers to be used according to the invention no protection is claimed within the scope of the invention.

In den folgenden Beispielen wurde der Stockpunkt des Gasöls nach DIN 51583, die Filtrierbarkeit nach DIN 51770 gemäß Hagemann-Hammerich bestimmt.
