Description

Verfahren zur Herstellung von Hochdruckschmiermitteln Zusatz zum Patent 8'76 433 In der Patentschrift 876 437 ist ein Verfahren beschrieben, nach dem man fettstofffreie Zusätze, die einem Mineralöl Hochdruckeigenschaften, von guter Wirksamkeit verleihen, herstellen kann, wenn man auf Olefine Schwefelchlorür, das gegebenenfalls elementaren Schwefel gelöst enthalten kann, oder Schwefel und Chlor einwirken läßt und die dabei entstehenden chlor- und schwefelhaltigen Reaktionsprodukte als Zusatzstoffe verwendet. Vorzugsweise sind hierzu rein aliphatische Olefine geeignet. Es hat sich weiterhin gezeigt, daß sich Olefingemische, bei denen die Lage der Doppelbindung verschieden ist und die auch Diolefine enthalten, besonders eignen. Solche Olefingemische erhält man z. B. beim Spalten von Paraffinkohlenwasserstoffen, insbesondere bei der Dampfphasenspaltung fester Paraffine.Process for the production of high pressure lubricants. Patent addendum 8'76 433 In the patent specification 876 437 a method is described, according to which one Fat-free additives, which give a mineral oil extreme pressure properties, of good effectiveness lend, can produce, if one on olefins sulfur chloride, which optionally may contain dissolved elemental sulfur, or allows sulfur and chlorine to act and the resulting chlorine and sulfur-containing reaction products as additives used. Purely aliphatic olefins are preferably suitable for this purpose. It has also shown that olefin mixtures in which the position of the double bond is different and which also contain diolefins, are particularly suitable. Such mixtures of olefins you get z. B. when splitting paraffinic hydrocarbons, especially in the vapor phase splitting of solid paraffins.

Neben den oben beschriebenen Olefingemischen eignen sich für die Darstellung der erfindungsgemäßen Zusatzstoffe auch Olefingemis che, die Doppelbindungen in den Seitenketten eines aromatischen oder naphthenischen Ringes enthalten, wie sie z. B. bei der Spaltung von Rückstandsölen oder ähnlichen Ausgangsmaterialien auf Erdölbasis, entstehen. In die Erfindung sind auch Olefingemische auf synthetischer Basiis einbegriffen.In addition to the above-described olefin mixtures are suitable for the representation of the additives according to the invention also Olefingemis che, the double bonds in contain the side chains of an aromatic or naphthenic ring, as they do z. B. in the cleavage of residual oils or similar starting materials Petroleum base. The invention also includes olefin mixtures on a synthetic basis Basiis included.

Es wurde nun gefunden, daß man die Wirkung als Hochdruckvermittler noch steigern kann, wenn man die als Ausgangsmaterial dienenden Olefine zunächst mit geringen Mengen Polymerisations-, katalys,ato@ren, wie z. B. Metallhalogeniden, Aluminiumchloriden usw. vorbehandelt und erst das dabei erhaltene Reaktionsgemisch, wie in dem Hauptpatent beschrieben, mit Schwefelchlorür, das gegebenenfalls elementaren Schwefel gelöst enthalten kann, oder mit Schwefel und Chlor zur Reaktion bringt. Diese Arbeitsweise hat gegenüber der des Hauptpatentes den Vorteil, daß man auch niedrigsiedende Olefingemische mit niedrigem Flammpunkt als Ausgangsmaterial verwenden kann, weil durch die polymerisierende Wirkung der Aluminiumchloridbehandlung der Flammpunkt so erhöht wiTä, daß er den Anforderungen des Grundöles, dem der Zusatz beigefügt werden soll, entspricht. Günstig wirkt sich dann, wie bereis erwähnt, die Polymerisationsreaktion auch auf die Wirksamkeit des erfindung.sigemäß beschriebenen Zusatzstoffes in jeder Richtung aus. Die Aluminiumchloridbehandlung kann durch gleichzeitigen Zusatz beider Stoffe bzw. der Zugabe eines Teils des einen oder anderen Stoffes erfolgen.It has now been found that one has the effect as a high-pressure mediator can increase, though one that serves as the starting material Olefins initially with small amounts of polymerization, catalysis, ato @ ren, such as. B. Metal halides, aluminum chlorides, etc. pretreated and only the one obtained thereby Reaction mixture, as described in the main patent, with sulfur chloride, which optionally May contain elemental sulfur dissolved, or react with sulfur and chlorine brings. This mode of operation has the advantage over that of the main patent that low-boiling olefin mixtures with a low flash point are also used as the starting material can use because of the polymerizing effect of the aluminum chloride treatment the flash point is so increased that it meets the requirements of the base oil to which the additive should be attached, corresponds. As already mentioned, it then has a beneficial effect the polymerization reaction also affects the effectiveness of what is described according to the invention Additive in each direction. The aluminum chloride treatment can be carried out by simultaneous Addition of both substances or the addition of part of one or the other substance take place.

Die Aluminiumchloridbehandlung nimmt man am besten bei Temperaturen von a5 bis 85° vor. Die ; Menge des Aluminiumchlorids richtet sich nach der Art des olefinausgangsmaterials, und beträgt in der Regel o,5 bi,s 3/G.The aluminum chloride treatment is best used at temperatures from a5 to 85 ° in front. The ; The amount of aluminum chloride depends on the type of the olefin starting material, and is usually 0.5 bi, s 3 / G.

Nach beendeter Reaktion verbleibt der mit dem Kondensationsmittel gebildete Schlamm im Reaktionsgut, das anschließend mvtWasser zersetzt wird. Etwa zu leicht siedende Anteile können zur Erreichung eines gewünschten Flammpunktes im Vakuum bei möglichst niedriger Temperatur abdestilliert werden.After the reaction has ended, the one with the condensing agent remains sludge formed in the reaction product, which is then decomposed with water. Approximately Too low-boiling fractions can be used to achieve a desired flash point be distilled off in vacuo at the lowest possible temperature.

Man kann auch so verfahren, daß man den mit dem Kondensationsmitrtlel gebildeten Schlamm abtrennt und allein mit Wasser zersetzt. Das bei dieser Zersetzung anfallende Ö1 stellt dann nach Konzentration auf den gewünschten Schlammpunkt einen äußerst wirksamen Hochdruckzusatz dar.One can also proceed in such a way that the one with the condensation agent sludge formed is separated and decomposed with water alone. That with this decomposition Accumulated oil then sets one after concentration on the desired sludge point extremely effective high pressure additive.
