Description

Verfahren zur Herstellung kolloider Lösungen.Process for the preparation of colloidal solutions.

Die bei der Herstellung kolloider Lösungen benutzten Schutzkolloide sind oft von ausschlaggebendem Einfluß auf das Gelingen des Herstellungsverfahrens. The protective colloids used in the manufacture of colloidal solutions are often of decisive influence on the success of the manufacturing process.

Die Erfindung bezieht sich auf die Auswahl bestimmter Schutzkolloide, die sich zur Herstellung von Lösungen organischer Kolloide und insbesondere auch anorganischer Kolloide eignen. Die Erfindung besteht in der Verwendung von Ablaugen, welche bei der Vergärung von Sulfitablauge abfallen; die Verwendung dieser Ablaugen kann im eingedickten oder nicht eingedickten Zustande erfolgen. Besonders gute Ergebnisse erzielt man, wenn die Sulfitablauge vor oder nach der Vergärung entkalkt und gereinigt wird. The invention relates to the selection of certain protective colloids, which are suitable for the preparation of solutions of organic colloids and in particular also inorganic colloids are suitable. The invention consists in the use of waste liquors, which fall from the fermentation of sulphite waste liquor; the use of these waste liquors can take place in the thickened or non-thickened state. Particularly good results can be achieved if the sulphite liquor is decalcified and cleaned before or after fermentation will.

Beispiele: I. Destilliertes Wasser wird mit so viel eingedickter, neutralisierter, entkalkter, vergorener Sulfitablauge versetzt, daß es 50 Prozent organische Substanz (nach der Glühmethode) enthält. In diese Lösung wird unter kräftigem Rühren in an sich bekannter Weise gleichzeitig Schwefelwasserstoff und schweflige Säure eingeleitet. Es entsteht, besonders wenn man abkühlt, ein Schwefelsol von geringer Teilchengröße und hervorragender Haltbarkeit. Examples: I. Distilled water is thickened with so much neutralized, decalcified, fermented sulphite liquor added that it is 50 percent contains organic substance (according to the annealing method). In this solution is under vigorous Stirring in a manner known per se at the same time hydrogen sulphide and sulphurous Acid initiated. Particularly when you cool down, a sulfuric brine of small particle size and excellent durability.

2. 1 1 Maschinenöl wird mit 200 g der oben beschriebenen, auf soProzent organische Substanz eingedickten, vergorenen Sulfitablauge in einem Porzellanmörser mit einem Pistill verrieben. Man erhält eine haltbare Emulsion, die sich mit Wasser verdünnen läßt. 2. 1 1 machine oil is 200 g of the above-described, to 50 percent Organic matter thickened, fermented sulphite waste liquor in a porcelain mortar rubbed with a pestle. A long-lasting emulsion is obtained that can be mixed with water can be diluted.

Auch andere Öle und Fette lassen sich in dieser Weise emulgieren, wobei die Menge des zuzusetzenden Schutzkolloides den jeweiligen Verhältnissen angepaßt werden muß. Other oils and fats can also be emulsified in this way, the amount of protective colloid to be added being adapted to the respective conditions must become.
