Description

Verfahren zur Herstellung klarer, hellgelber, pharmazeutisch wertvoller Öle. Die Erfindung bezieht sich 'auf ein Verfahren zur Herstellung klarer, hellgelber Öle von geringem, teils nicht unangenehmen, teils angenehmen Geruche aus bituminösem Rohöl unter gleichzeitiger Gewinnung brauchbarer Nebenprodukte ohne Verlust an Ausgangsmaterial.Process for making clear, light yellow, pharmaceutically valuable Oils. The invention relates to a method for producing clear, light yellow Oils with low, partly not unpleasant, partly pleasant smells from bituminous Crude oil with simultaneous recovery of usable by-products without loss of starting material.

Das Verfahren beruht in folgendem: , r. Das Rohöl wird einer Destillation unterworfen, welche bei etwa 116' C beginnt und bei der die Temperatur schließlich bis auf a90 bis 300° C gesteigert wird; dabei hinterbleiben 5o Prozent des Ausgangsmaterials als ein dicker schwarzer Teer, der als solcher zu allen entsprechenden Verwendungsarten völlig tauglich ist.The procedure is based on the following:, r. The crude oil undergoes a distillation which starts at about 116 ° C and at which the temperature finally occurs is increased up to a90 to 300 ° C; this leaves 5o percent of the starting material as a thick black tar, which as such can be used for all corresponding types of use is completely suitable.

2. Die überdestillierten Öle werden mit etwa 2/3 ihres Gewichtes gebranntem Kalk (Ca O) und 1-/Z, festem Ätzkalium oder natrium (Ko H oder Na O H) 6 bis io Stunden am Rückflußkühler bis zum Sieden erhitzt und dann abdestill:iert.2. The distilled oils are burned with about 2/3 of their weight Lime (Ca O) and 1- / Z, solid caustic potassium or sodium (Ko H or Na O H) 6 to io Heated to boiling on the reflux condenser for hours and then distilled off.

3. Dieses C51 wird mit i Prozent Äthylalkohol und 5 Prozent Natriummetäll versetzt und i bis 2 Tage dieser Reduktion überlassen und dann filtriert oder abgezogen.3. This C51 is made with 1 percent ethyl alcohol and 5 percent sodium metal added and left to this reduction for 1 to 2 days and then filtered or stripped off.

q.. Durch Waschen wit Wasser kann dem leicht alkalischen öle seine Alkalität genommen werden, wenn das wünschenswert erscheint.q .. By washing with water, the slightly alkaline oils can be Alkalinity should be taken if that appears desirable.

5. Durch Schütteln des Öles mit 5oprozen- . tiger Schwefelsäure, wobei vorn der Säure % des Ölvolumens genügt, erhält man ein neutrales C51, das einen an Lindenblüten erinnernden Geruch aufweist.5. By shaking the oil with 5%. tiger sulfuric acid, where if the acid% of the oil volume is sufficient, a neutral C51 is obtained, the one has an odor reminiscent of linden blossoms.

An Stelle des Waschens mit Wasser kann auch eine nochmalige Destillation mit Vorteil eingeschaltet werden.Instead of washing with water, another distillation can also be carried out be switched on with advantage.

Die Öle sind auf Grund von Versuchen zur Behandlung von Erkrankungen der Haut und ihrer Gebilde bei Menschen und Tieren bestimmt, wobei direkte Anwendung und Bereitung von Salben zunächst in Aussicht genommen sind; die Durcharbeitung dieser Anwendungsgebiete, die vermutlich auch deren Erweiterung zur Folge haben wird, wird von medizinischen Fachleuten erfolgen.The oils are based on attempts to treat diseases the skin and its structures in humans and animals determined, with direct application and the preparation of ointments are initially envisaged; working through these areas of application, which will probably also lead to their expansion will be done by medical professionals.
