Description
Verfahren zur Herstellung eines wasserlöslichen, festen Gemisches von Alkalisilicaten und Alkaliacetaten Mischungen von festen Alkalisilicaten, die alkaliärmer als Metasilicate sind, mit festen Alkaliacetaten können durch Mischen der einzelnen festen Bestandteile hergestellt werden. Es ist dabei notwendig, daß die festen Alkaliacetate in einem gesonderten Verfahren gewonnen werden und sie dann mit den festen Alkalisilicaten vermischt werden. Die Gemische lösen sich ungleichmäßig in Wasser, da sich von den beiden Bestandteilen Alkaliacetate erheblich schneller lösen.Process for the preparation of a water-soluble, solid mixture of alkali silicates and alkali acetates Mixtures of solid alkali silicates, the Are lower in alkali than metasilicates, with solid alkali acetates can be obtained by mixing of the individual solid components are produced. It is necessary that the solid alkali acetates are obtained in a separate process and they then mixed with the solid alkali silicates. The mixtures dissolve unevenly in water, since alkali acetates differ considerably more quickly from the two components to solve.
Es wurde nun gefunden, daß besonders gleichmäßige und innige, wasserlösliche, feste Gemische von Alkalisilicaten und Alkaliacetaten ohne von festen Alkalisalzen ausgehen zu müssen und ohne Anwendung besonderer Mischvorrichtungen gewonnen werden können, wenn man eine wäßrige Lösung von AlkalLmetasilicat mit Essigsäure bis zur beginnenden Ausscheidung von Kieselsäure versetzt und dann das Reaktionsprodukt bis zum Erhalt eines festen Produktes eindampft. überraschenderweise kann man dabei einen erheblichen Betrag an Essigsäure zusetzen, bis bleibende Ausscheidungen von Kieselsäure auftreten. Bei entsprechender Bemessung des Säurezusatzes kann man einen nach dem Ein, dampfen praktisch neutralen, wasserlöslichen Rückstand erhalten.It has now been found that particularly uniform and intimate, water-soluble, solid mixtures of alkali silicates and alkali acetates without solid alkali salts have to go out and be obtained without the use of special mixing devices can, if an aqueous solution of alkali metal metasilicate with acetic acid up to incipient precipitation of silica added and then the reaction product evaporated until a solid product is obtained. Surprisingly you can do it add a significant amount of acetic acid until permanent excretions of Silica occur. With an appropriate dimensioning of the acid addition one can use one after evaporation, a practically neutral, water-soluble residue is obtained.
Die gemäß der Erfindung erhaltenen Salzgemische stellen in Form wäßriger Lösungen ein wirksames Reinigungsmittel z. B. für Metalle, Textilien usw. dar.The salt mixtures obtained according to the invention are in the form of aqueous ones Solutions an effective detergent e.g. B. for metals, textiles, etc.
Beispiel Zu 2,81 Silicatlösung, welche r4oo g Natriummetasilicat (wasserfrei) enthält, läßt man unter Rühren in der" Wärme bei etwa 6o° C bis zur bleibenden Trübung Eisessig zutropfen, wofür etwa 700 ccm erforderlich sind. Von Eisessig gibt man zweckmäßig etwa das letzte Drittel mit Wasser verdünnt zu. Nach dem Eindampfen der Flüssigkeit bleibt ein leicht mahlbarer Rückstand, der aus einer wasserhaltigen Mischung von etwa q.4o,'o Natriumacetat und 56% Natriumsilicat besteht und in Wasser leicht löslich ist.EXAMPLE Glacial acetic acid is added dropwise to 2.81 silicate solution, which contains 400 g of sodium metasilicate (anhydrous), while stirring in the heat at about 60 ° C. until it remains cloudy, for which about 700 cc is required The last third is diluted with water. After evaporation of the liquid, an easily grindable residue remains, which consists of a water-containing mixture of about 40% sodium acetate and 56% sodium silicate and is easily soluble in water.
