Description

Verfahren zur Herstellung von Umwandlungsprodukten von Torf und von Braunkohle Im Patent 72o 828 ist ein Verfahren zur Herstellung von Umwandlungsprodukten von Torf und von Braunkohle zur Gewinnung von Emulgatoren für Asphalt- und ülemulsionen beschrieben, das dadurch gekennzeichnet ist, daß mit Alkalien aufgeschlossene Braunkohle ,oder ebenso aufgeschlossener Torf, bei gewöhnlichem Druck und höherer Temperatur in Gegenwart von Katalysatoren mit Ozon behandelt, die Reaktionsmasse angesäuert und mit organischen Lösungsmitteln extrahiert, und der nach dem Verdampfen des Lösungsmittels erhaltene Rückstand mit Alkalien verseift wird.Process for the production of conversion products of peat and of Brown coal In the patent 72o 828 is a process for the production of conversion products of peat and lignite for the extraction of emulsifiers for asphalt and oil emulsions described, which is characterized in that lignite digested with alkalis , or also digested peat, at ordinary pressure and higher temperature treated with ozone in the presence of catalysts, acidifying the reaction mass and extracted with organic solvents, and that after evaporation of the solvent obtained residue is saponified with alkalis.

Das Ansäuern des Reaktionsproduktes und Extrahieren mit .organischen Lösungsmitteln war nötig, damit die Huminsäuren entfeYnt werden, da diese die- Emulgatoren in ihrem Wirkungsgrad stark beeinträchtigen. Es wurde nun gefunden, daß man die Herstellung der Umlvandlungsprodukte umgekehrt wie im Patent 720 828 vornehmen kann, d. h. man trennt zunächst durch selektive Lösungsmittel die unlöslichen Huminsäuren von den übrigen Bestandteilen ab. Die erhaltene Lösung wird vom Lösungsmittel befreit und der Rückstand dann mit Alkali aufgeschlossen und mit Ozon oxydiert. Die oxydierte alkalische Lösung kann bei geeigneter Konzentration ohne weitere Behandlung als EmulgatoT verwendet werden. Hierdurch wird das Ansäuern vermieden und eine Vereinfachung des Verfahrenserzielt.The acidification of the reaction product and extraction with .organischen Solvents were necessary so that the humic acids are removed, as these are the emulsifiers severely impair their efficiency. It has now been found that the Production of the conversion products can be carried out in reverse as in patent 720 828, d. H. the insoluble humic acids are first separated using selective solvents from the other components. The solution obtained is freed from the solvent and the residue then digested with alkali and oxidized with ozone. The oxidized alkaline solution can be used as a suitable concentration without further treatment EmulgatoT can be used. This avoids acidification and simplifies the process of the process.

Beispiel i oo kg Braunkohle oder Torf werden zunächst mit Äther in der Wärme behandelt, wodurch die unlöslichen Huminsäuren abgetrennt werden. Der vom Äther befreite Extrakt wird mit i kg Natriumhydroxyd und i oo kg Wasser im Autoklaven bei 6 at Druck und 16o bis 17o° verrührt. Nach i Stunde wird unter ständigem Umrühren nach Zusatz von o,5kg Bleilinoleat bei gewöhnlichem Druck und 7 o bis 8o° i Stunde Ozon eingeleitet. Die so erhaltene Lösung kann direkt als Emulgator für Asphalt- und ölemulsionen dienen.Example i oo kg of lignite or peat are first mixed with ether in the heat treated, whereby the insoluble humic acids are separated will. The extract, freed from the ether, is mixed with 1 kg of sodium hydroxide and 100 kg of water stirred in the autoclave at 6 atm pressure and 16o to 17o °. After one hour, under constant stirring after adding 0.5kg lead linoleate at normal pressure and 7 ° to 80 ° 1 hour ozone was introduced. The solution obtained in this way can be used directly as an emulsifier serve for asphalt and oil emulsions.
