Description

Verfahren zum Reinigen oder Trennen von Gemischen von fetten oder mineralischen Ölen oder Destillations- oder Hydrierungsprodukten von Kohle usw. Bei der Reinigung oder Trennung von Ölen werden vielfach Verfahren benutzt, die ohne Destillation durch Extraktion oder Trennung mit Hilfe von Lösungsmitteln durchgeführt werden, z. B. die Entsäuerung von Ölen mit Hilfe von Alkoholen. Entparaffinierung von Teeren mit Aceton, die Raffinat ion von Schmierölen oder Isolierölen mit Hilfe von Methanol USW. Process for purifying or separating mixtures of fatty or mineral oils or distillation or hydrogenation products of coal, etc. In the purification or separation of oils, many processes are used which are carried out without distillation by extraction or separation with the aid of solvents, e.g. B. the deacidification of oils with the help of alcohols. Dewaxing of tars with acetone, the raffinat ion of lubricating oils or insulating oils with the help of methanol, etc.

Es wurde nun gefunden, daß als Lösungsmittel für die Reinigung oder Trennung von fetten oderminera'ischenÖlen oderDestillations-oder Hydrierungsprodukten von Kohle usw. mit Vorteil die Formiate der niederen Alkohole der Fettreihe oder Gemische solcher verwendet werden können. Besonders vorteilhaft ist die Verwendung von Methylformiat, das z. B. aus Methylalkohol und Kchlenoxyd sehr leicht gewonnen werden kann; infolge seines niedrigen Siedepunkts läßt es sich sehr einfach von denExtrakten abtrennen. Das Methylformiat kann auch in wasserhaltiger Form angewendet werden. Beispiel t Sesamöl mit -ro °;o freier Säure wird dreimal mit der- dreifachen Merge Methylformiat, das 5 °/o Wasser enthält, behandelt= Der Säuregehalt geht dadurch auf 0,20/0 zurück. Beispiel 2 Ein Destillat von mexikanischem Rohöl wird mehrere Male mit Methylformiat im Verhältnis _ : z ausgeschüttelt. Es wird hierbei ein helles, nicht mehr nachdunkelndes Öl erhalten, das völlig fr( i von dem unangenehmen Geruch des ursprünglichen Produktes ist. Der Schwefelguhalt ist von 2,3 °/o auf o,6 °/o zurückgegangen.It has now been found that as a solvent for cleaning or Separation of fatty or mineral oils or distillation or hydrogenation products of coal etc. with advantage the formates of the lower alcohols of the fatty series or Mixtures of these can be used. The use is particularly advantageous of methyl formate z. B. obtained very easily from methyl alcohol and calcium oxide can be; due to its low boiling point, it can be easily removed from separate the extracts. The methyl formate can also be used in water-containing form will. Example t sesame oil with -ro °; o free acid is three times with-threefold Merge methyl formate, which contains 5% water, treated = the acidity goes through to 0.20 / 0. Example 2 A Mexican crude distillate becomes several Shaken out times with methyl formate in the ratio _: z. It becomes a bright, no longer darkening oil is obtained, which is completely free of the unpleasant smell of the original product. The sulphurous content is from 2.3 per cent to 0.6 per cent decreased.

Beispiel 3 Ein bei der katalyti.chen Druckhydrierung eines Roherdöls nach Abdestillieren der niedrigsi(denden Anteile gewonnener ölartiger Rückstand wi:d mit einem Überschuß von Methylf@)rmiat, gegebenenfalls unter Erwärmung und kräftiger Rührung, behandelt. Der hierbei in Lösung gegangene Anteil stellt nach dem Abduns'en des Extraktionsmittels ein goldgelbe, wertvolles Harz dar.Example 3 In the catalytic pressure hydrogenation of a crude oil oily residue obtained after distilling off the low-sizing fractions wi: d with an excess of Methylf @) rmiat, optionally with heating and strong stirring, treated. The portion that went into solution in the process adjusts When the extraction agent is removed, a golden yellow, valuable resin is produced.
