Description

Verfahren zur Herstellung von Bleichstoff Die Gewinnung eines synthetischen Bleichstoffes durch Fällung von Alkalisilikat mit Magnesiumsalzen in Verbindung mit Kalisalzen ist im Patent 848 80I beschrieben, ferner ist im Patent 877 596 der Zusatz von Aluminiumsalzen zu den Magnesium-und Kalisalzen beschrieben.Process for the manufacture of bleach Obtaining a synthetic Bleaching agent by precipitation of alkali silicate with magnesium salts in connection with potassium salts is described in patent 848 80I, furthermore in patent 877 596 Addition of aluminum salts to the magnesium and potassium salts is described.

Ein Produkt von erheblich höherer Bleichwirkung wird erzielt durch Fällung von Alaunen des Aluminiums in Gemeinschaft mit anderen Elementen, welche Alaune bilden können. Hierbei ist gegenüber der schon im Patent 877 596 beschriebenen Verwendung von Aluminiumsulfat der Gehalt des Bleichmitteis an Kalium wichtig und neuartig. A product with a significantly higher bleaching effect is achieved through Precipitation of alums of aluminum in association with other elements, which Can form alums. This is opposite to that already described in patent 877 596 Using aluminum sulphate the potassium content of the bleach is important and novel.

An Stelle vorgebildeter Alaune können auch zur Bildung der Doppelsalze erforderliche Salze der dreiwertigen Elemente, z. B. Aluminiumsulfat, Eisensulfat u. dgl., mit Kaliumsulfat Verwendung finden. Instead of pre-formed alums, you can also create double salts required salts of the trivalent elements, e.g. B. aluminum sulfate, iron sulfate and the like, find use with potassium sulfate.

Beispiel I In eine Lösung von I8 g Aluminiumsulfat, 5 g Kaliumsulfat und 7 g Eisenkaliumalaun in 500 cmS Wasser wird eine Lösung von Alkalisilikat, die I6 g Natriumsilikat enthalten soll, bei Raumtemperatur oder höherer Temperatur eingerührt. Example I In a solution of 18 g of aluminum sulfate, 5 g of potassium sulfate and 7 g of iron potassium alum in 500 cmS of water becomes a solution of alkali silicate, which Should contain 16 g of sodium silicate, stirred in at room temperature or higher.

Der entstandene Niederschlag wird abgetrennt, ausgewaschen und getrocknet.The resulting precipitate is separated off, washed out and dried.

Beispiel II In eine wäßrige Lösung von Kaliwasserglas wird ein Salzgemisch von 4 Teilen Aluminiumkalialaun und I Teil Eisenkalialaun in fester Form so lange eingetragen, als noch eine Fällung zu erkennen ist. Der entstandene Niederschlag wird abgetrennt, ausgewaschen und getrocknet. Example II A salt mixture is placed in an aqueous solution of potassium waterglass of 4 parts of aluminum potash and 1 part of iron potash in solid form for so long entered when a precipitation can still be seen. The resulting Precipitate is separated off, washed out and dried.

PATENTANSPRCHE: I. Verfahren zur Herstellung von Bleichstoff, dadurch gekennzeichnet, daß man Aluminiumalkalialaune, die neben Kalium auch Eisen, Kobalt, Chrom, Nickel, Mangan oder andere Alaun bildende Schwermetalle enthalten, in Wasser löst, die Lösung mit Silikatlösungen niederschlägt und den von der Lösung abgetrennten Niederschlag trocknet. PATENT CLAIMS: I. Process for making bleach, thereby characterized that one aluminum alkali whites, which in addition to potassium also iron, cobalt, Chromium, nickel, manganese or other heavy metals that form alum are found in water dissolves, precipitates the solution with silicate solutions and the separated from the solution Precipitation dries.
