Description

Schmierfette Zusatz zum Patent '367, 323 Die vorliegende: Erfindung ist eine Weiterentwicklung der Verfahren nach den Patenten 767 323, 767 461, 767 414 und 767 413. Das Hauptpatent 767 323 hat ein Verfahren zum Gegenstand, nach dem für die Herstellung konsistenter Schmierfette die bei der Paraffinoxydation anfallenden Nach- und Vorlauffettsäuren mit einer größeren Kohlens.toffzahl als i9 allein oder in Mischung mit solchen einer kleineren Kohlenstoffzahl als 14 verwendet werden. Entsprechend der Erfindung ergab sich nunmehr, daß der Verwendung von Essigsäure als niedermolekularer Fettsäure mit einer Kohlenstoffzahl unter 14 zur Herstellung konsistenter Schmierfette eine besondere Bedeutung zukommt. Überraschenderweise zeigen konsistente Fette, die unter Mitverwendung von Essigsäure hergestellt werden, eine extrem hohen; Tropfpunkt bei weichester Konsistenz; was erfindungsgemäß dadurch erreicht wird, daß die Vorlauffettsäuren ganz oder teilweise durch Essigsäure ersetzt werden. Durch die Mitverwendung von Essigsäure können Schmierfette von weicher, zügiger Vaselinebeschaffenheit mit bisher- unerreicht hohen Tropfpunkten hergestellt werden. Die Mitverwendun- von Essigsäure eignet sich hei Fetten aller Art, unabhängig davon, mitteIs welcher b'asen bzw. mittels welcher sonstigen Seifenbildner. wie z. B. natürlichen Fetten. den natürlichen Fettsäuren entsprechende svntlietisclie Fettsäuren, hochmolekularen Fettsäuren mit einer hohlenstoffzahl über ig, niedermolekularen Fettsäuren mit einer Kohlenstoffzahl zwischen 3 und 14. Montanwachs u. a. m.. allein oder in Mischung, der Seifenkörper gebildet wird. Der Zusatz von Essigsäure kann durch Zumischen der Essigsäure zu den übrigen Seifenbildnern erfolgen, wobei eine äquivalente Erhöhung der anzuwendenden Basenmenge erfolgen muß; oder der Zusatz von Essigsäure kann durch 'Verwendung von Acetaten erfolgen, die dem Schmierfe ttansatz während des I-Terstellungs,-angzs hinzugefügt werden. Findet eine mehrsäurige Base, beispielsweise Kallzlit-drat Verwendung, so lassen sich Fette herstellen. deren Tropfpunkt die ioo°-Grenze überschreitet. Ganz besonders auffällig ist die durch Mitverwendung von Essigsäure bewirkte Tropfpunhtsteigerung bei natronverseiften Fetten. Bei der Herstellun- natronverseifter Schmierfette wurde beispielsweise gefunden, daß die zusätzliche Mitverwendung von etwa ;7% Essigsäure sawie der zugehörigen 1Jenge Natronlauge eine Steigerung des Tropfpunktes von iig° auf 210° bewirkt. ferner wird die Konsistenz durch den Essigsäurezusatz weich und zügig und ähnlich der Konsistenz von Vaseline.Lubricating Greases Addendum to Patent '367,323 The Present: Invention is a further development of the process according to patents 767 323, 767 461, 767 414 and 767 413. The main patent 767 323 has a method for the subject, according to that for the production of consistent lubricating greases that of paraffin oxidation accumulating post and first fatty acids with a higher carbon number than i9 used alone or in a mixture with those with a carbon number smaller than 14 will. According to the invention it has now been found that the use of acetic acid as a low molecular weight fatty acid with a carbon number below 14 for production Consistent lubricating greases are of particular importance. Surprisingly show consistent fats that are produced with the use of acetic acid, an extremely high one; Dropping point with the softest consistency; what according to the invention thereby what is achieved is that the first run fatty acids are completely or partially replaced by acetic acid will. By using acetic acid, lubricating greases from soft, faster Vaseline quality with unprecedented high dropping points getting produced. The use of acetic acid is suitable for all fats Type, regardless of the means of which bases or which other soap formers. such as B. natural fats. svntlietisclie corresponding to the natural fatty acids Fatty acids, high molecular weight fatty acids with a carbon number higher than IG, low molecular weight Fatty acids with a carbon number between 3 and 14. Montan wax and others. m .. alone or in a mixture, the soap body is formed. The addition of acetic acid can by adding the acetic acid to the remaining soap formers, with one an equivalent increase in the amount of base to be used must take place; or the addition Acetic acid can be done by using acetates, which add to the lubricant approach during the creation, -angzs be added. Finds a polyacid base for example kallzlit-drat use, so fats can be produced. whose Dropping point exceeds the 100 ° limit. It is particularly noticeable through The use of acetic acid resulted in an increase in the drip point in the case of soda-saponified products Fats. In the production of sodium saponified lubricating greases, for example, it was found that that the additional use of about; 7% acetic acid as the associated 1The amount of sodium hydroxide solution causes an increase in the dropping point from iig ° to 210 °. further the consistency becomes soft and quick and similar to the consistency due to the addition of acetic acid of petroleum jelly.

Die 1Iä@iehkeit, sehr weiche Schmierfette von extrem hohem Tropfpunkt herstellen zu können. eröffnet den erfindungsgemäß hergestellten Schmierfetten besondere Anwendungsgebiete, für die es bisher keine befriedigenden Schmiermittel gab. Beispielsweise werden schnell laufende Kugellager zweck: Vermeidung von Energieverlusten mit reiner weicher Vaseline geschmiert. obwohl der Schmierwert. besonders die Druckbeständigkeit der Vaseline nur gering ist. Außerdem besitzt Vaseline nur einen sehr geringen Tropf@unla, so dar' ihre Verwendung als Schmierfett für warm laufende Kugellager ausscheiden muß.
