Zusätze für SchmiermittelAdditives for lubricants

Es wurde gefunden, daß sich solche Benzidinverbindungen, deren Aminogruppen durch je mindestens einen Cyclohexylrest substituiert sind, hervorragend zur Verwendung als Schmiermittelzusätze eignen. Außer den X-Cyclohexylderivaten des ßenzidins selbst können dabei auch durch Alkyl-, Oxalkyl- oder Cycloalkylgruppen kernsubstituierte X-Cyclohexylderivate des ßenzidins verwendet werden.It has been found that such benzidine compounds whose amino groups are each substituted by at least one cyclohexyl radical, excellent for use as lubricant additives. Except for the X-cyclohexyl derivatives of the benzidine itself can also be obtained by means of alkyl, oxyalkyl or cycloalkyl groups Nuclear-substituted X-cyclohexyl derivatives of ßenzidine be used.

Die erforderliche Menge an den neuen Schmierstoffzusatzmitteln läßt sich durch Vorversuche jeweils leicht ermitteln; im allgemeinen genügen Mengen von etwa o.i bis 0.5 Gewichtsprozent, bezogen auf das Gesamtschmiermittel.The required amount of the new lubricant additives can easily be determined by preliminary tests; generally enough Amounts from about o.i to 0.5 percent by weight, based on the total lubricant.

Die vorgeschlagenen Zusatzmittel sind in Schmierölen auf Mineralölbasis gut und klar löslich; die hiermit versehenen Öle zeichnen sich durch eine hohe Heständigkeit gegenüber Luftsauerstoff aus. Sie neigen dabei nicht zur A^erfärbung, die häufig bei anderen Zusätzen aminogruppenhaltiger Verbindungen zu beobachten ist. Falls gewünscht, kann man den Schmiermitteln außer den vorgeschlagenen Zusatzmitteln auch andere Mittel beimischen, etwa solche, die die Schmierfilmfestigkeit bei hohen Drücken erhöhen, wie z. ß. Phosphorverbindungen gemäß den Patenten 851237 und 879 138.The proposed additives are readily and clearly soluble in lubricating oils based on mineral oil; the oils provided with this are characterized by a high level of resistance to atmospheric oxygen the end. They do not tend to discolour, which is often the case with other additives containing amino groups Connections is observed. If desired, one can use the lubricants other than those suggested Additives also add other agents, such as those that improve the strength of the lubricating film increase at high pressures, e.g. ß. Phosphorus compounds according to patents 851237 and 879 138.

Beispielexample

Einem Mineralölraffinat auf Paraffinbasis von der Qualität eines Turbinenöles werden 0,2 Gewichtsprozent X. X"'-Bicyclohexyl-3, 3'-dimethylbenzidin unter leichtem Erwärmen zugesetzt.A paraffin-based mineral oil raffinate of the quality of a turbine oil is 0.2 percent by weight X. X "'- Bicyclohexyl-3,3'-dimethylbenzidine added with slight warming.

Wird das Öl einem Alterungstest unterworfen, bei dem die Sauerstortaufnahme bei 1500 und in Gegenwart von Kupferpulver durch den Druck-If the oil is subjected to an aging test in which the oxygen uptake at 150 0 and in the presence of copper powder by the pressure

abfall an einem Quecksilbermanometer verfolgt werden kann, so ergibt sich durch den Zusatz der genannten Eenzidinverbindung eine erhebliche Verzögerung in der Sauer stoff auf nähme. Während das Öl ohne Zusatz der Benzidinverbindung schon nach 5 Minuten einen Druckabfall von ioo mm Hg zeigt, wird dieser Abfall in Gegenwart der Benzidinverbindung erst nach etwa 260 Minuten beobachtet; ähnlich liegen die Verhältnisse, wenn das Öl z. B. eine Phosphorverbindung von der Art des Bis-(p-chlor-plienyl)-phosphinsäure-butylesters enthält. Setzt man statt des N, N'-Dicyclohexyl-3, 3'-dimethyl-benzidins das N, N'-Dicyclohexyl-3, 3'-diäthoxy-benzidin als Schmierstoffzusatzmittel ein, so liegt die Verzögerung der Sauerstoffaufnahme in der gleichen Größenordnung.waste can be tracked on a mercury manometer, results from the addition of the called eenzidine compound a considerable Delay in the oxygen absorption. While the oil does without the addition of the benzidine compound shows a pressure drop of 100 mm Hg after 5 minutes, this drop in the presence of the Benzidine compound only observed after about 260 minutes; The situation is similar if the oil z. B. a phosphorus compound of the bis (p-chloro-plienyl) -phosphinic acid butyl ester type contains. If instead of the N, N'-dicyclohexyl-3, 3'-dimethyl-benzidine N, N'-dicyclohexyl-3, 3'-diethoxy-benzidine as a lubricant additive a, the delay in oxygen uptake is of the same order of magnitude.

Prüft man das als Schmierstoffzusatzmittel bereits vorgeschlagene Dibenzoylbenzidiii oder Dibenzylidenbenzidin unter denselben Bedingungen, so tritt der Druckabfall von 100 mm Hg bereits nach 10 Minuten ein.If you check the dibenzoylbenzidiii or already proposed as a lubricant additive Dibenzylidenebenzidine under the same conditions, the pressure drop of 100 mm Hg already occurs after 10 minutes.
