Description

Schmiermittel Die Erfindung betrifft die Verwendung von noch freie Hydroxylgruppen enthaltenden Estern des Pentaerythrits mit einem Gemisch niedermolekularer Fettsäuren als Schmiermittel. Es ist zwar bekannt, Ester von niedermolekularen Säuren für Schmierzwecke zu verwenden, jedoch stellten sie keine vom Pentaerythrit dar; außerdem hat man sie nur in relativ kleinen Beimengungen zu bekannten Kohlen-Wasserstoffölen hinzugegeben, während der vorliegende Ester für sich allein verwendet werden kann. Der Pentaerythritester weist im Gegensatz zu Schmiermitteln bekannter Konstitution, wie Klauenöl, Kohlenwasserstoffen u. dgl., den Vorteil auf, keine Neigung zur Verharzung oder Polymerisation zu besitzen. Außerdem zeichnet sich der Ester durch tiefen Stockpunkt aus.Lubricants The invention relates to the use of still free Esters of pentaerythritol containing hydroxyl groups with a mixture of low molecular weight Fatty acids as lubricants. Although it is known to use esters of low molecular weight acids to be used for lubrication purposes, however they were not of pentaerythritol; in addition, they are only found in relatively small admixtures to known carbon-hydrogen oils added, while the present ester can be used alone. In contrast to lubricants of known constitution, the pentaerythritol ester such as neat oil, hydrocarbons and the like, have the advantage of no tendency to resinify or to possess polymerization. In addition, the ester has a low pour point the end.

Die Verwendung von Estern mehrwertiger Alkohole mit Fettsäuren eines mittleren Molekulargewichts von iio bis 175 ist nicht Gegenstand des Patents. Gegenüber diesen Maßnahmen bietet das neue Schmiermittel den Vorteil, daß durch die noch vorhandenen freien Hydroxylgruppen im Ester der Stockpunkt und die Viskosität weiter günstig beeinflußt werden. Als saure Komponente verwendet man zweckmäßig ein Gemisch niedermolekularer Fettsäuren aus der Kohlenwasserstoffoxydation, insbesondere dasjenige, das zwischen etwa zoo bis r4öö bei 3 bis 4 mm Vakuum siedet.The use of esters of polyhydric alcohols with fatty acids having an average molecular weight of from 10 to 175 is not the subject of the patent. Compared to these measures, the new lubricant has the advantage that the pour point and viscosity are further favorably influenced by the free hydroxyl groups still present in the ester. A mixture of low molecular weight fatty acids from hydrocarbon oxidation is expediently used as the acidic component, in particular that which boils between about zoo to r4öö at a vacuum of 3 to 4 mm.
