PATENTAMT. \%PATENT OFFICE. \%

Bei der Entfärbung, Reinigung und Raffination von Fetten, Paraffin, Oelen u. dgl. durch Behandlung mit Entfärbungs- und Reinigungspulvern (Bleicherden) hat sich der Uebelstand gezeigt, dafs die Reinigungsmittel eine beträchtliche Menge Fett u. dgl. (bis zu 40 pCt.) zurückhalten. Die Gewinnung dieser noch zu verwerthenden Fett- bezw. Paraffin- und OeI-rückstände ist erwünscht, um das zu bearbeitende Material vollkommen auszunutzen und das Reinigungspulver wieder verwendungsfähig zu machen.When decolorizing, cleaning and refining fats, paraffin, oils and the like Treatment with decolorizing and cleaning powders (bleaching earth) has become a problem has shown that the cleaning agents retain a considerable amount of grease and the like (up to 40 pct.). The extraction of this still to be used fat respectively. Paraffin and oil residues is desirable in order to fully utilize the material to be processed and to make the cleaning powder reusable close.

Es hat sich aber gezeigt, dafs die Wiedergewinnung dieser oft beträchtlichen Rückstände so grofse technische Schwierigkeiten bereitet, dafs z. B. die Raffination mit anorganischen Erden theilweise ganz aufgegeben, theilweise nur mit wenig Vortheil ausgeführt wurde. Die jetzt meist gebräuchlichen Entfettungsverfahren mit Lösungsmitteln, wie Benzin, sind infolge der Feuergefährlichkeit unbequem und kostspielig.

Auch durch die gelegentlich erwähnte Behandlung mit heifsem Wasser (Patentschrift 27333) wird dieser Uebelstand nicht vermieden, so dafs noch eine Extraction mit ihren Nachtheilen nothwendig ist.It has been shown, however, that the recovery of these often considerable residues so great technical difficulties that z. B. refining with inorganic It was partly abandoned and partly carried out with little advantage. the The most common degreasing processes with solvents such as gasoline are now a consequence the fire hazard inconvenient and costly. The "Aussc, hrnelzu_ng" der ^ JFeJte, "jQele ujid ... of paraffin with water. .istJechnischudes-Jialb ^ junggejgneJL, ,, because-the, light voluminous created the fine powder one. sufficient .scharfe ^^ Trerinling ,, desJF'ettes. ^. yon ,, dem.Pulper.

Also by the occasionally mentioned treatment with hot em Water (Patent Specification 27333) this disadvantage is not avoided, so that an extraction is necessary with its disadvantages is necessary.

Dagegen hat sich gezeigt, dafs bei Behandlung der Entfärbungspulver mit Wasser unter Druck bei höherer Temperatur eine vollkommene Abscheidung des Fettes und ähnlicher Stoffe gelingt, so dafs das Fett auf dem Wasser schwimmt, während das Entfärbungspulver von dem Fett getrennt ist. Zu gleicher Zeit werden auch in sehr erheblicher Menge die färbenden Stoffe, zu,deren Entfernung die Bleicherden gedient haben, beseitigt, so dafs auch_ein_e WiederhalekHftg-rler letzteren stattfindet.On the other hand, it has been shown that when the decolorizing powder is treated with water under pressure at a higher temperature, a complete separation of the fat and similar substances succeeds, so that the fat floats on the water, while the decolorizing powder is separated from the fat. At the same time also be in very considerable amount of coloring matters, to the removal of which have served the bleaching earths removed; so that also _ein_e Repeat latter takes place alekHftg-rler.

~verseifbafen" Fetten findet bei dem Verfahren eine Spaltung in Glycerin und Fettsäure statt, wodurch aber eine Verwendung des wiedergewonnenen Fettes nicht verhindert wird, weil das mit Farbstoffen, Harz u. dgl. gesättigte, in den Rückständen gebliebene und aus denselben wiedergewonnene Fett nur für die Seifenfabrikation verwendet werden kann, für welche die Spaltung des Fettes aber durchaus nicht schädlich ist.~ saponifiable "fats take place in the process a cleavage into glycerol and fatty acid takes place, which, however, results in the use of the recovered fat is not prevented because the saturated with dyes, resin and the like, fat remaining in the residues and recovered from them only for them Soap production can be used, for which the splitting of the fat but definitely is not harmful.

Die Ausführung des Verfahrens geschieht am besten im Autoclaven bei einer Temperatur,, die erheblich über 100 ° C. liegt, vortheilhaft z. B. bei 1800C. Man kann das zu behandelnde Pulver eventuell auch in ein Tuch einschliefsen, um die Trennung des Fettes vom Pulver zu erleichtern. Nothwendig ist die Anwendung von DampL. „bezw Wasse?7" unterThe process is best carried out in an autoclave at a temperature which is well above 100 ° C., advantageously e.g. B. at 180 ° C. You can possibly also enclose the powder to be treated in a cloth in order to facilitate the separation of the fat from the powder. The use of DampL is necessary. "Or water? 7" below

This makes it possible to remove the grease from cleaning agents except for a fraction of a percent.
