   Verfahren zur Beseitigung der bei der Reinigung von Fettstoffen, Harzen und Kohlenwasserstoffen mit Alkalien oder Erdalkalien entstehenden Elmulsion. 



   Bei der Reinigung der Fette und fetten Öle mittels Alkalien oder Erdalkalien besteht eine grosse Gefahr darin, dass bei der Temperatur, bei der die Behandlung ausgeführt werden muss, namentlich wenn die   Behandlung längere   Zeit dauert, die angewendeten Stoffe   schädigend auf   die Fette selbst einwirken, so dass sie zu vielen Zwecken, beispielsweise zu   Speisezwecken,   unbrauchbar werden. 



   Um diese schädlichen Nebenwirkungen der Reagentien aufzuheben, hat man Schutzmittel   angewendet,   beispielsweise Kohle oder Walkerde, und ferner ist in Deutschland durch das D.   R.     l*.   Nr.   143946 dem Erfinder seihst   ein Verfahren geschützt, durch welches die Zeitdauer der Einwirkung der Alkalien oder alkalischen Erden ausserordentlich abgekürtz und somit die   schädigenden Einwirkungen   der Reagentien vermieden werden, indem die entstandene und mit einem Schutzmittel von Walkerde oder Kohle gemischte Seifenemulsion einem geringen Dampfüberdruck von etwa · bis 1· Atm. ausgesetzt wird.

   Wenn nun auch dieses Verfahren sehr gute Resultate liefert, so ist doch die aus der Anwendung von Dampf resultierende Erhöhung der Temperatur über den Siedepunkt immer noch ein Übel, welches bisher als nicht vermeidbar in den Kauf genommen werden musste und welches

   Process for the elimination of the Elmulsion formed during the cleaning of fatty substances, resins and hydrocarbons with alkalis or alkaline earths.



   When cleaning fats and fatty oils with alkalis or alkaline earths, there is a great danger that at the temperature at which the treatment has to be carried out, especially if the treatment lasts for a long time, the substances used have a damaging effect on the fats themselves that they become unusable for many purposes, for example for food purposes.



   In order to reverse these harmful side effects of the reagents, protective agents have been used, for example coal or fuller's earth, and furthermore, in Germany by the D. R. l *. No. 143946 the inventor is protected by a process by which the duration of the action of the alkalis or alkaline earths is extremely shortened and thus the damaging effects of the reagents are avoided by using the soap emulsion, mixed with a protective agent of fulling earth or coal, at a low steam pressure of about · to 1 · Atm. exposed.

   Even if this method also gives very good results, the rise in temperature above the boiling point resulting from the use of steam is still an evil, which up to now had to be accepted as unavoidable and which

 capable of not only fats and fatty oils but also resins. Purify trane and hydrocarbons in this way.



   The fat to be freed from the emulsion is heated up to 85 ° C in a closed vessel, for example, after the air present in this has been replaced by nitrogen,

PATENTANSPRUCH : EMI2.1 Verfahren zur. Beseitigung der beider Reinigung von Fettstoffen, Harzen und Kohlen- wasserstoffen mit Alkalien oder Erdailcalien entstehenden Emulsion mittels Druck, dadurch gekennzeichnet, dass man den Druck nicht durch Dampf, sondern durch indifferente Gase erzeugt, zu dem Zwecke, Druck und Temperatur voneinander unabhängig zu machen und eine Erniedrigung der letzteren unter die für die Fette schädliche Grenze zu eermöglichen. PATENT CLAIM: EMI2.1 Procedure for. Elimination of the emulsion resulting from the cleaning of fatty substances, resins and hydrocarbons with alkalis or Erdailcalien by means of pressure, characterized in that the pressure is generated not by steam but by inert gases, for the purpose of making pressure and temperature independent of one another and to allow the latter to be lowered below the limit harmful to fats.
