Description
Verfahren zur Verbesserung von Schmierstoffen Bekanntlich wird die Schmierfähigkeit von Schmierstoffen unter der Einwirkung höherer Temperaturen, wie sie beispielsweise im Betrieb von Bren.nkraftmaschinen auftreten, stark herabgesetzt. Diese Herabsetzung beruht nicht nur auf der mit der Temperaturerhöhung Hand in. Hand gehenden. Verflüssigung, sondern, geht in ganz beträchtlichem Maße auf die Rückstandsbildung, Verharzung u. dgl. zurück. So wird beispielsweise derSchmierfilm an derZylind.er'wand nach gewisser Zeit unter Umständen bei gleichzeitiger Rückstandsbildung zerstört, wodurch Leistungsabfall und sogar oft die Zerstörung der Brennkraftmaschine- eintritt.Process for improving lubricants It is known that the Lubricity of lubricants under the influence of higher temperatures, such as they occur, for example, in the operation of Bren.nkraftmaschinen, greatly reduced. This reduction is not only due to that which goes hand in hand with the increase in temperature. Hand going. Liquefaction, rather, goes to quite a considerable extent on that Residue formation, resinification and the like back. For example, the lubricating film on the cylinder wall after a certain time, possibly with simultaneous residue formation destroyed, which leads to a drop in performance and often even the destruction of the internal combustion engine entry.
Es wurde gefunden, daß die Bildung von koblenstoffreichen: Rückständen. verlangsamt, herabgesetzt wird oder in weniger betriebsstörender Form geschieht, wenn man .dem Schmierstoff Zusätze von chemischen Verbindungen beigibt, die folgendermaßen gekennzeichnet werden können.: R- (SX) -A.It has been found that the formation of carbon-rich residues. is slowed down, reduced or occurs in a less disruptive manner, when adding chemical compounds to the lubricant, these are as follows can be marked: R- (SX) -A.
Hierbei bedeutet R einen aliphatischen oder aromatisch-aliphatischen Rest, der auch über eine urganische-Oxy- oder: Thiosäure mit der folgenden Säure SX, die eine mehrbasische anorganische Säure, beispielsweise eine Sauerstoffsäure des Schwefels darstellt, und entweder über eine 0-oder S-Brücke wie auch direkt --finit dem Zentralatom der Säure verknüpft sein kann. A ist schließlich das Kation einer anorganischen oder organischen Base bzw. Ammonium oder -ein Homologes davon z. B. Pyridinium.Here, R denotes an aliphatic or aromatic-aliphatic Rest who also have a urganische-oxy- or: thio-acid with the following acid SX, which is a polybasic inorganic acid, for example a Oxygen acid of sulfur represents, and either via an O or S bridge as can also be directly --finitely linked to the central atom of the acid. A is after all the cation of an inorganic or organic base or ammonium or a homologue of which z. B. pyridinium.
V er Iindungen dieser Art sind z. B. Dodeyl# natriumsuffat, Oleylnatriumsulfat, Alkylpyridiniumsülfat oder Verbindungen von Ryp R- O C O (CH2) n S S 03 Na.Connections of this type are e.g. B. Dodeyl sodium sulfate, oleyl sodium sulfate, Alkylpyridinium sulphate or compounds of Ryp R- O C O (CH2) n S S 03 Na.
Diese Stoffe setzen allein und in Gemischen, besonders aber auch bei Gegenwart niederer organischer Fettsäuren und ihrer Salze, wie z. B.. Propionsäure, bei Zusatz ih gelöster oder höchdisperser Form die Rückstandsbildung und Verharzung im Verbrennungsraum von Brennikraftmaschinen herab.These substances are used alone and in mixtures, but especially also with Presence of lower organic fatty acids and their salts, such as. B. Propionic acid, with the addition of dissolved or highly dispersed form, the formation of residues and resinification in the combustion chamber of internal combustion engines.
Den Beweis hierfür liefert der Rngstecklauf, bei dem bekanntlich die Zeit gemessen -wird, nach der eine, Brennkra_ftmäschine unter ganz bestimmten Bedingungen einen Leirstungsabfall durch Steckenbleiben -der Kolbenringe verrät. Die Laufzeit der Brennkraftmaschine bei der Ringsteckprobe wird durch das Zusetzen der öbengenannten Mittel zum Schmieröl um 15 0lo und mehr erhöht.Proof of this is provided by the Rngstecklauf, in which, as is well known, the Time is measured, according to the one, Brennkra_ftmaschine under very specific conditions a drop in performance due to the piston rings getting stuck. the period the internal combustion engine in the ring plug-in test is achieved by adding the above-mentioned Medium for lubricating oil increased by 150,000 and more.
Die erforderliche Menge des Zusatzes, ist etwa ein Bruchteil eines Prozentes der Menge des Schmierstoffes. Zu- i5.1 Schmieröl werden beispielsweise 30 9 Oleylnatriumsulfat und 8 ccm Propionsäure, gelöst in 0o ccm .Ben2ol-Äthanol-Gemisch I : i, zugesetzt.The amount of additive required is approximately a fraction of a percent of the amount of lubricant. To i5.1 lubricating oil, for example, 30 9 oleyl sodium sulfate and 8 cc propionic acid, dissolved in 0o cc .ben2ol-ethanol mixture I: i, are added.
