Description

Herstellung von in mineralkohlenwasserstoffen löslichen Ölen aus Ricinusöl Ricinusöl ist bekanntlich infolge seiner hohen Viskosität, seiner Kältebeständigkeit und seiner geringen Oberflächenspannung ein vorzügliches Schmiermittel. Die Verwendung dieses Öles in unvermischtem Zustand ist aber infolge seines hohen Preises nur für ganz besondere Zwecke möglich. Der Vermischung von Ricinusöl mit Mineralschmierölen steht andererseits seine nahezu vollkommene Unlöslichkeit in diesen Ölen entgegen. Die Aufgabe, das Ricinusöl mit Mineralölen mischbar, d. h. in Mineralölen klar löslich zu machen, ist noch nicht zufriedenstellend gelöst worden. Das bekannte Verfahren, durch das dem Ricinusöl diese Eigenschaft dadurch erteilt wird, daß es der destruktiven Destillation unterworfen wird, bis etwa 5 °f, Destillat ,übergegangen.sind (Vgl. Patent ro4499),b'efriedigt nicht.Production of oils soluble in mineral hydrocarbons from castor oil Castor oil is well known due to its high viscosity, its resistance to cold and its low surface tension makes it an excellent lubricant. The usage this oil in the unmixed state is only for very special purposes possible. Mixing castor oil with mineral lubricating oils on the other hand, it is almost completely insoluble in these oils. The task of making the castor oil miscible with mineral oils, d. H. Clearly soluble in mineral oils to make has not yet been solved satisfactorily. The well-known procedure by which the castor oil is given this property by virtue of the fact that it is destructive Is subjected to distillation until about 5 ° f, distillate, have passed (cf. Patent ro4499), not satisfactory.

Man kann auch Lösungen von Ricinusöl in Mineralöl dadurch erhalten, daß man Ricinusöl mit C51- oder Fettsäuren unter Zusatz von Mineralöl bei gewöhnlichem Druck erhitzt. Die so gewonnenen Öle enthalten aber erhebliche Mengen freier öl- oder Fettsäuren und sind daher für Schmierzwecke in diesem Zustand nicht geeignet. Sie müssen daher einem umständlichen Entsäuerungsprozeß mit Soda unterworfen werden. Außerdem sind diese Mischungen nicht haltbar, da sie sich bei Abkühlung in Schichten trennen.One can also obtain solutions of castor oil in mineral oil by that one castor oil with C51 or fatty acids with the addition of mineral oil with ordinary Pressure heated. The oils obtained in this way contain considerable amounts of free oil or fatty acids and are therefore not suitable for lubrication purposes in this state. You must therefore be subjected to a cumbersome deacidification process with soda. In addition, these mixtures are not durable, as they become in layers when cooled separate.

Es wurde nun gefunden, daß man zu fast säurefreien und- in Mischung mit Mineralöl auch bei starker Abkühlung haltbaren Erzeugnissen gelangt, wenn man Ricinusöl mit Öl- oder Fettsäuren unter vermindertem Druck auf Temperaturen von etwa Zoo bis 25o° erhitzt.It has now been found that almost acid-free and mixed With mineral oil, products that can be kept even when cooled down can be obtained, if one Castor oil with oleic or fatty acids under reduced pressure to temperatures of about zoo heated to 25o °.

Die erhaltenen Erzeugnisse können nicht nur zur Herstellung von Schmiermitteln, sondern auch für andere technische Zwecke benutzt werden.The products obtained can be used not only for the production of lubricants, but can also be used for other technical purposes.

Beispiel i 75 g Ricinusöl werden mit a5 g Ölsäure im Vakuum sechs Stunden lang auf 23o° erhitzt. Das erhaltene Kondensationsprodukt löst sich in jedem Verhältnis in Mineralöl. Säurezahl des Gemisches vor dem Erhitzen = 514 nach dem Erhitzen = 4,3.Example i 75 g of castor oil are mixed with a5 g of oleic acid in vacuo Heated to 23o ° for hours. The obtained condensation product dissolves in each Ratio in mineral oil. Acid number of the mixture before heating = 514 after Heating = 4.3.

Beispiel z 8o g Ricinusöl werden mit 2o g Stearinsäure im Vakuum vier Stunden auf 22o° erhitzt. Das erhaltene Kondensationsprodukt löst sich in jedem Verhältnis in Mineralöl. Säurezahl vor dem Erhitzen = 48,6, nach dem Erhitzen = 5,4.Example z 80 g of castor oil are four with 20 g of stearic acid in a vacuum Heated to 22o ° for hours. The obtained condensation product dissolves in each Ratio in mineral oil. Acid number before heating = 48.6, after heating = 5.4.
