Description

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

Die Erfindung betrifft ein Verfahren zur Herstellung kolloidaler Lösungen, insbesondere anorganischer Stoffe, speziell von Metalloiden. The invention relates to a method for producing colloidal Solutions, especially of inorganic substances, especially of metalloids.

Es besteht darin, daß man eine wäßrige Abkochung von Reisig oder Rinde von Hölzern, insbesondere von Koniferenhölzern, wie solche z. B. in der Patentschrift 340289 angegeben sind, als Schutzkolloid verwendet. Man kann diese Abkochung mit oder ohne Druck durchführen und die erhaltene Kochflüssigkeit beliebig eindicken bzw. die Abkochung selbst als Lösungsmittel verwenden. It consists in making an aqueous decoction of sticks or Bark of wood, especially conifer wood, such as such. B. in the patent 340289 are given, used as protective colloid. You can use this decoction or without pressure and thicken the resulting cooking liquid as desired or use the decoction itself as a solvent.

Beispiele: i. Zur Herstellung einer kolloiden Schwefellösung versetzt man z. B. i 1 Wasser mit 50g der oben genannten Abkochung, die auf einen Gehalt von ungefähr 50 Prozent organischer Substanz eingedickt ist, und leitet in an sich bekannter Weise gleichzeitig Schwefelwasserstoff und Schwefeidioxyd unter Rühren, gegebenenfalls unter Abkühlung, in das Wasser ein. Es entsteht eine haltbare, feindisperse Lösung von kolloidem Schwefel. Examples: i. Added to the preparation of a colloidal sulfur solution one z. B. i 1 water with 50g of the above decoction, which on a content is thickened by about 50 percent organic matter, and derives in itself as is known, at the same time hydrogen sulfide and sulfur dioxide with stirring, possibly with cooling, into the water. The result is a durable, finely dispersed one Solution of colloidal sulfur.

2. ii Maschinenöl wird mit 200 g der in der Beschreibung genannten Abkochung (die auf einen Gehalt von 50 Prozent organischer Substanz eingedickt ibt) in einem Porzellanmörser mit einem Pistill innig verrieben. 2. ii machine oil is 200 g of that mentioned in the description Decoction (thickened to a level of 50 percent organic matter) thoroughly rubbed in a porcelain mortar with a pestle.

Man erhält eine haltbare Emulsion, die sich weitgehend mit Wasser verdünnen läßt.A long-lasting emulsion is obtained, which is largely diluted with water can be diluted.

3. 100 ccm der filtrierten Abkochung, die in bezug auf organische Substanz einprozentig ist, wird mit 10 ccm 1/10 n. Silbernitrat versetzt, und hierauf werden 10 ccm 1/10 n. Jodkalium hinzugefügt. Es bildet sich sofort beim Verrühren in der Kälte eine haltbare Lösung von Jodsilber, die sich in der Wärme(z. B. bei 850) konzentrieren läßt. Die Lösung kann durch Dialyse gereinigt werden. 3. 100 cc of the filtered decoction relating to organic Substance is one percent, 10 ccm 1/10 normal silver nitrate is added, and then 10 cc 1/10 n. potassium iodine are added. It forms immediately when stirred in the cold a durable solution of iodized silver, which in the warm (e.g. in 850) lets you concentrate. The solution can be purified by dialysis.

4. 100 ccm der filtrierten Abkochung werden mit ioccm llto n. Silbernitrat versetzt. 4. 100 cc of the filtered decoction are mixed with 100 cc of silver nitrate offset.

Beim Erwärmen auf etwa 700 erhält man das durch die reduzierende Wirkung des Pinons entstandene Silber in haltbarer kolloider Lösung. Die Lösung läßt sich in der Wärine konzentrieren und kann nötigenfalls durch Dialyse gereinigt werden.When heated to around 700, this is achieved through the reducing effect The silver produced by the pinon in a durable colloidal solution. The solution can be Concentrate in the heat and can be cleaned by dialysis if necessary.

Auch andere Öle und Fette lassen sich in dieser Weise in eine wäßrige Emulsion überführen, wobei die Menge des zuzusetzenden Schutzkolloides den Bedürfnissen entsprechend variiert werden muß. Other oils and fats can also be converted into an aqueous one in this way Transfer emulsion, the amount of protective colloid to be added meeting the needs must be varied accordingly.
