Description

Verfahren zur Herstellung metalloxydhaltiger Sole Zusatz zum Patent 582 682 In dem Hauptpatcnt 582 682 ist ein Verfahren zur Herstellung metalloxydhaltiger Sole bzw. hochdisperser Suspensionen beschrieben, das darin besteht, daß man bei der Einwirkung von Äthylenoxyd auf Salze von Schwer-oder Erdmetallen entstehende Reaktionsgemische mit Lösungsmitteln für Glykolester und Äthylenoxyd extrahiert.Process for the production of sols containing metal oxides. Patent addition 582 682 In the main patent 582 682 is a process for the production of metal oxide Soles or highly dispersed suspensions described, which consists in that one with the action of ethylene oxide on salts of heavy metals or earth metals Reaction mixtures extracted with solvents for glycol esters and ethylene oxide.

Es wurde nun gefunden, daß man für die Herstellung der Sole an Stelle von Äthylenoxyd auch andere Alkylenoxyde, z. B. Propylenoxyd, benutzen kann, wobei die Extraktion mit Lösungsmitteln für solche Alkylenoxyde und für die bei der Reaktion entstehenden Ester durchzuführen ist. Der Vorteil der Benutzung von insbesondere Propylenoxyd besteht darin, daß man hierbei nicht mit bei gewöhnlicher Temperatur gasförmigen Substanzen arbeiten muß, sondern mit Flüssigkeiten arbeiten kann, und daß außerdem hochwertige Ester als Nebenprodukte gewonnen werden. It has now been found that for the preparation of the brine in place of ethylene oxide also other alkylene oxides, z. B. propylene oxide, can use, wherein extraction with solvents for such alkylene oxides and for those involved in the reaction resulting ester is to be carried out. The advantage of using in particular Propylene oxide consists in the fact that you do not use it at ordinary temperature gaseous substances must work, but can work with liquids, and that high-quality esters are also obtained as by-products.

B e i s p i e l 1 600 Volumteile einer 25 Obigen Lösung von kristallisiertem Aluminiumchlorid werden mit 120 Volumteilen Propylenoxyd etwa 2 Tage lang bei 30" stehengelassen oder während mehrerer Stunden in verschlossenem Gefäß aut 60 bis 100° erhitzt. Die Reaktionsmischung wird alsdann zwecks Entfernung gebildeten Propylenchlorhydrins und etwa überschüssigen Propylenoxyds mit Äther extrahiert. Man erhält eine klare Lösung von Aluminiumhydroxyd, die im Liter etwa 50 g Al 03, teilweise als Ahiminiumoxychlorid, enthält. For example, 1 600 parts by volume of the above solution of crystallized Aluminum chloride is mixed with 120 parts by volume of propylene oxide for about 2 days at 30 " left to stand or for several hours in a closed vessel for 60 to 100 ° heated. The reaction mixture is then formed to remove propylene chlorohydrin and any excess propylene oxide extracted with ether. You get a clear Solution of aluminum hydroxide containing about 50 g of Al 03 per liter, partly as ammonium oxychloride, contains.

Beispiel -500 ccm einer 20%igen wäßrigen Zinkchloridlösung werden unter Rühren allmählich mit go ccm Propylenoxyd versetzt. Das nach mehrstündigem Stehen erhaltene Sol, in dem sich noch feste Teilchen in feiner Verteilung befinden, wird hierauf mit Äthylenchlorid extrahiert; durch Zugabe von z. B. nach dem Verfahren des Hauptpatents hergestellten Aluminiumhydroxydsol werden alsdann die fein verteilten suspendierten Teile in noch feinere Verteilung übergeführt. Example -500 ccm of a 20% aqueous zinc chloride solution 3 cc of propylene oxide are gradually added while stirring. That after several hours Are obtained sol, in which there are still solid particles in fine distribution, is then extracted with ethylene chloride; by adding z. B. after the procedure The aluminum hydroxide sols produced in the main patent are then finely divided suspended parts converted into an even finer distribution.
