Verfahren zur iawse^w&taaisr*von Schmierfetten,Procedure for iawse ^ w & taaisr * of lubricating greases,
Schmierfette werden üblicherweise aus Seifen und Kohlenwaaaerstoffölen, insbesondere Hineralölfraktionen, hergestellt» Dabei vermischt man in der Regel zur Seifenbildung befähigte organische Verbindungen, insbesondere pflanzliche oder tierische fette» Montan·= wachs, Tallöl oder die in diesen Stoffen enthaltenen fettsäuren oder auch synthetische, vor allem durch Oxydation hochmolekularer aliphatischer Kohlenwasserstoffe, wie Paraffin, hergestellte fettsäuren, mit geeigneten Fraktionen ron Kohlenwasserstoffölen und unterwirft die Masse einer Verseifung mit einer oder mehreren basischen Verbindungen, insbesondere Natronlauge oder gelöschtem Kalk oder beiden* Die Eigenschaften! der erhaltenen Schmierfette lassen sich durch die Γ/ahl der Kohlenwasserstofföle und der seifenbildenden organischen Verbindungen und deren Mengenverhältnisse, sowie durch die Art der basischen Verbindungen weitgehend beeinflussen«Jedoch genügen die Fette nicht immer allen Anforderungen, die sich bei der Schmierung ergeben»Lubricating greases are usually made from soaps and hydrocarbon oils, especially bottled oil fractions, produced »here As a rule, organic compounds capable of forming soaps are mixed, in particular vegetable or animal fats »Montan · = wax, tall oil or the fatty acids contained in these substances or synthetic fatty acids, especially those produced by oxidation of high molecular weight aliphatic hydrocarbons such as paraffin, with suitable fractions of hydrocarbon oils and subjects the mass to saponification with one or more basic compounds, in particular caustic soda or slaked lime or both * The properties! of the greases obtained through the variety of hydrocarbon oils and soap-forming oils Organic compounds and their proportions, as well as the nature of the basic compounds largely influence «However the greases do not always meet all the requirements that arise during lubrication »
Zur Verbesserung der Eigenschaften der Fette hat man bereits vorgeschlagen, neben den seifenbildenden organischen Verbindungen aach noch andere saure Stoffe, z.B, Benzoesäure,mitzuvorwenden, die bei der Verseifung ebenfalls in Salze übergeführt werden. Auch die so hergestellten Fette lassen jedoch in manchen Fällen noch Wünsche offen»In order to improve the properties of fats, it has already been proposed, in addition to the soap-forming organic compounds also other acidic substances, e.g. benzoic acid, must also be used, which are also converted into salts during saponification. In some cases, however, the fats produced in this way still do not Wishes open »
Es wurde nun gefunden, dass man bei dem zuletzt genannten Verfahren besonders gute Ergebnisse erhält, wenn man als sauren Zusatz-It has now been found that the last-mentioned method particularly good results are obtained when the acidic additive
stoff das rohe Gemisch aromatischer 'Carbonsäuren rerwendet9 das durch Oxydation ron Toluol mit Salpetersäure erhalten «vurde and vornehmlich Benzoesäure enthält» Die Verwendung einer solchen Ben soesäure hat den Vorteil9 dass die Säure wesentlich billiger ist als die handelsübliche reine Benzoesäure ο Trotzdem erhalt man Schmierfette, die den mit reiner Benzoesäure hergestellten mindestens gleichwertig und ihnen oft überleben sind3 Diese Vorteile werden in allen fällen erzielt, einerlei ob man mit Alkalien, insbesondere Watronlauge, oder Erdalkalien, Tor allem Calciumhydroxyd, oder deren Mischungen verseifteThe raw mixture of aromatic carboxylic acids is used 9 which is obtained by oxidation of toluene with nitric acid «and mainly contains benzoic acid» The use of such a benzoic acid has the advantage 9 that the acid is considerably cheaper than the commercially available pure benzoic acid ο Nonetheless, you get lubricating greases which are at least equivalent to those made with pure benzoic acid and which often survive 3 These advantages are achieved in all cases, regardless of whether one saponifies with alkalis, especially water hydroxide, or alkaline earths, especially calcium hydroxide, or mixtures thereof
