Description
Verfahren zur Herstellung von Starrschmieren. Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung von Starr schmieren, das heisst von Mineralöl enthal tenden Emulsionen salbenartiger Konsistenz. Das Verfahren ist dadurch gekennzeichnet, dass man hydroxylierte Fette, die animalischen oder vegetabilischen Ursprunges sein können, Mineralöl und hochkonzentriertes Alkali mit einander mischt. Unter hydrogylierten Fetten sind Stoffe zu verstehen, die durch Behandlung von oleinreichen vegetabilischen oder anima lischen Fetten mit Schwefelsäure und nach trägliches Kochen mit Wasser erhältlich sind.
Solche hydroxylierte Fette, allein oder im Gemisch mit andern Fetten, haben die Ei genschaft, grosse Mengen von Kohlenwasser- stoffen aufzunehmen. Mischt man zum Bei spiel einem Mineralöl, zum Beispiel Spindelöl, eine Fettsäure bei und verseift mit Alkali, so bilden sich im Gemenge einige Seifen klumpen, die sich beim Stehen absetzen.
Gibt man dagegen mit der Fettsäure noch hydro- xyliertes Fett zu, so löst sich die gebildete Seife im Mineralöl auf und das Gemisch erstarrt zu einer salbenartigen, homogenen Masse, die als Starrschmiere verwendbar ist und einen Tropfpunkt von 90 bis 200 und darüber aufweisen kann, je narb Konzentra tion der verwendeten Alkalilauge und der Art der Fettsäure.
Man kann gemäss dem Verfahren tech nisch verwendbare Fette erhalten, die voll kommen neutral und wasserarm sind, in ihrem Aussehen ganz den durch galkverseifung erhaltenen Fetten gleichen, letzteren aber durch ihren hohen Schmelzpunkt und gerin gen Aschengehalt überlegen sind. Das Ver fahren kann bei gewöhnlicher oder nur wenig erhöhter Temperatur durchgeführt werden. Es ist zweckmässig, aber nicht notwendig, den bydroxylierten Fetten als Zusatzstoffe neutrale Fette oder Wachse oder höhere Fettsäuren oder Gemische solcher Stoffe zuzusetzen.
Je nach der Zusammensetzung des Aus gangsgemisches kann man mittelst des Ver fahrens salbenartige Transparentfette, wasser lösliche Fette, sogenannte Calypsolfette von gummiartiger Konsistenz und hohem Tropf punkt, sowie sogenannte Fettbriketts, das heisst harte Fette mit hohem Tropfpunkt, herstellen, und zwar besteht der Vorteil des vorliegenden Verfahrens gegenüber den bisher bekannten Verfahren zur Herstellung dieser Fette darin, dass man auf kaltem bis halb warmem Wege arbeiten kann, während man bisher bis zum Siedepunkt erhitzen musste.
Das Alkali, zum Beispiel Natron oder Kali, kann in Form hochkonzentrischer Lösun gen, aber auch in Staubform angewendet werden. Je höher die Konzentration desto zweckmässiger ist eine Erhöhung der Tem peratur, die' jedoch<B>750</B> C nicht zu über steigen braucht.
Es hat sich gezeigt, dass nach dem Ver fahren die hydroxylierten Fette bis zum 15fachen ihres Gewichtes an Mineralölen aufnehmen können.
<I>Beispiele:</I> 1. 50 kg hydroxyl;ertes Fett und 50 kg einer hochmolekularen Fettsäure werden bei möglichst niederer Temperatur geschmolzen und gut gemischt. 10 kg der so erhaltenen Masse werden mit 88 kg Mineralöl gernischt und dann 2 kg 50 /o ige Natronlauge zuge setzt. Man könnte auch zuerst das Mineralöl mit der Natronlauge versetzen und dann die 10 kg der oben genannten Masse zugeben.
2. 90 kg Spindelöl, 5 kg eines hydroxy- lierten Fettes und 5 kg einer hochrnoleku- larerr Fettsäure werden kalt oder unter leichtem Erwärmen innig gemischt und bei einer Temperatur von 20-30" C mit der zur Verseifung der Fettsäure nötigen Menge Natronlauge von 38-50o B6 versetzt.
Process for the production of rigid lubrication. The present invention relates to a process for the production of rigid lubricate, that is to say emulsions of ointment-like consistency containing mineral oil. The process is characterized in that hydroxylated fats, which can be of animal or vegetable origin, mineral oil and highly concentrated alkali are mixed with one another. Hydrogylated fats are understood to mean substances that are obtainable by treating olein-rich vegetable or animal fats with sulfuric acid and then boiling them with water.
Such hydroxylated fats, alone or in a mixture with other fats, have the property of absorbing large quantities of hydrocarbons. If, for example, a mineral oil, for example spindle oil, is mixed with a fatty acid and saponified with alkali, some lumps of soaps form in the mixture, which settle when standing.
If, on the other hand, hydroxylated fat is added along with the fatty acid, the soap formed dissolves in the mineral oil and the mixture solidifies into an ointment-like, homogeneous mass that can be used as a solid smear and can have a dropping point of 90 to 200 and above, Depending on the concentration of the alkali lye used and the type of fatty acid.
According to the process, technically usable fats can be obtained which are completely neutral and low in water, resemble the fats obtained by calcium saponification in their appearance, but are superior to the latter due to their high melting point and low ash content. The process can be carried out at normal or only slightly elevated temperature. It is useful, but not necessary, to add neutral fats or waxes or higher fatty acids or mixtures of such substances to the hydroxylated fats.
Depending on the composition of the starting mixture, the process can be used to produce ointment-like transparent fats, water-soluble fats, so-called calypsol fats with a rubber-like consistency and a high dropping point, and so-called fat briquettes, i.e. hard fats with a high dropping point, which has the advantage of present process compared to the previously known processes for the production of these fats in that you can work on a cold to half warm route, while previously you had to heat up to the boiling point.
The alkali, for example soda or potash, can be used in the form of highly concentrated solutions, but also in the form of dust. The higher the concentration, the more appropriate it is to increase the temperature, which, however, does not need to exceed <B> 750 </B> C.
It has been shown that after the process the hydroxylated fats can absorb up to 15 times their weight in mineral oils.
<I> Examples: </I> 1. 50 kg of hydroxylated fat and 50 kg of a high molecular weight fatty acid are melted at the lowest possible temperature and mixed well. 10 kg of the mass thus obtained are mixed with 88 kg of mineral oil and then 2 kg of 50% sodium hydroxide solution are added. You could also first add the sodium hydroxide solution to the mineral oil and then add the 10 kg of the above-mentioned mass.
2. 90 kg spindle oil, 5 kg of a hydroxylated fat and 5 kg of a high molecular weight fatty acid are intimately mixed cold or with slight warming and at a temperature of 20-30 "C with the amount of 38 sodium hydroxide solution required to saponify the fatty acid -50o B6 offset.
