Description
Verfahren zur Reinigung von Kieselsäureestern von anhaftenden Säurespuren Zusatz zur Patentanmeldung D 30362 TVb/l2 o (Auslegeschrift 1093 343) Die Hauptpatentanmeldung D 30362 IVb/ 12o beschreibt ein Verfahren zur Reinigung von Kieselsäureestern von anhaftenden Säurespuren durch Einrühren von Metallen der II. Gruppe des Periodischen Systems der Elemente, z. B. von Zink oder Magnesium in Pulverform.Process for cleaning silicic acid esters from adhering traces of acid Addition to patent application D 30362 TVb / l2 o (Auslegeschrift 1093 343) The main patent application D 30362 IVb / 12o describes a process for the purification of silicic acid esters from adhering traces of acid by stirring in metals of group II of the periodic System of elements, e.g. B. of zinc or magnesium in powder form.
Es wurde nun gefunden, daß auch Metalle der III., IV., VI. und VIII. Gruppe des Periodischen Systems der Elemente oder auch deren Metallegierungen für dieses Verfahren geeignet sind und restlichen Halogenwasserstoff unter Bildung von Halogeniden entfernen. Dabei kann die Anwendung in Form von Staub oder in gröberer Verteilung erfolgen, z. B. in Form von Metallspänen. It has now been found that metals of III., IV., VI. and VIII. Group of the Periodic Table of the Elements or their metal alloys for this process are suitable and residual hydrogen halide with the formation of Remove halides. The application can be in the form of dust or coarser Distribution take place, e.g. B. in the form of metal chips.
Beispiel 1 Bei der Herstellung von Athylsilikat aus SiCl4 und Äthyl alkohol kann der Säuregehalt durch Austreiben des Alkoholüberschusses nur bis auf etwa 0,5 0/o erniedrigt werden. Anschließendes, stundenlanges Durchleiten von trockener Luft erniedrigt den Säuregehalt noch auf etwa 0,20/0, aber weiter nicht. Ein Zusatz von 0,4 Gewichtsprozent Fe-Staub bringt den Ester in kurzer Zeit zu neutraler Reaktion. Example 1 In the production of ethyl silicate from SiCl4 and ethyl Alcohol can only reduce the acidity by driving out the excess alcohol about 0.5% can be lowered. Subsequent passage of dry for hours Air lowers the acidity to about 0.20 / 0, but not further. An addition of 0.4 percent by weight Fe dust brings the ester to a neutral reaction in a short time.
Beispiel 2 In der gleichen Weise, wie bei Beispiel 1 beschrieben, wird an Stelle von Fe-Staub, Al-Staub verwendet und die Temperatur des Esters auf 700 C gebracht. Example 2 In the same way as described in Example 1, is used in place of Fe dust, Al dust and the temperature of the ester increases 700 C.
Des weiteren sind Zinn, Nickel und Chrom geeignet, wobei in der Weise verfahren wird, wie in den Beispielen 1 und 2 angegeben. Es können auch Metallegierungen. wie z. B. eine Magnesium-Aluminium-Legierung angewendet werden. Furthermore, tin, nickel and chromium are suitable, and in the manner the procedure is as indicated in Examples 1 and 2. Metal alloys can also be used. such as B. a magnesium-aluminum alloy can be used.
Beispiel 3 Es wird wie im Beispiel 1 verfahren, nur werden Späne einer Magnesium-Aluminium-Legierung angewendet. Example 3 The procedure is as in Example 1, except that there are chips a magnesium-aluminum alloy.
