Description

Verfahren zur Herstellung beständiger wässeriger, kolloidaler Lösungen von 19letalloiden. Es wurde gefunden, daß man z. B. phar-. lnazeutisch oder für die Schädlingsbekämpfung wertvolle kolloidale Lösungen von Metalloiden, insbesondere von Schwefel, Selen, Phosphor und Arsen erhält, wenn man eine Lösung des Metalloids in Sohwefelkohlen-stoff mit Wasser oder einer wässerigen Lösung in Gegenwart von Schutzkolloiden Vermischt und das Lösungsmittel durch mäßiges Erhitzen, oder einen indifferenten Gasstrom oder beide Mittelentfernt. Man kann dabei die Mengenverhältnisse manni:gfaltig wechseln und auch ,gleichzeitig mehrere Schutzkolloide verwenden. Das Schutzkolloid kann entweder der Ausgangslösung oder dem Wasser zugefügt werden. Be4sp.iel i. i Teil einer gesättigten Lösung - von Schwefel in Schwefelkohlenstoff wird mit 2 bis 3 Teilen einer 35prozentigen Seifenlösung gerührt oder ,geschüttelt. D:ie dabei entstehende rahmige Flüssigkeit lößt sich in Wasser zu einer beständigen weißen Schwefelemulsion auf, aus der man den Schwefelkohlenstoff leicht durch Erwärmen oder Hindurchleiten eines indifferenten Gasstromes austreiben kann. Man kann auch weitere Schutzkolloide, z. B. Sapon:i-n, lysalbi.nsaures Natrium usw., zufügen.Process for the preparation of stable aqueous, colloidal solutions of 19 lethalloids. It has been found that z. B. phar-. lnazeutisch or for pest control valuable colloidal solutions of metalloids, in particular of sulfur, selenium, phosphorus, and arsenic, if one obtains a solution of the metalloid in carbon disulfide with water or an aqueous solution in the presence of Protective colloids Mixed and the solvent by moderate heating, or one indifferent gas flow or both means removed. You can use the proportions manni: change frequently and also use several protective colloids at the same time. The protective colloid can either be added to the starting solution or to the water. For example i. i part of a saturated solution - of sulfur in carbon disulfide is stirred or shaken with 2 to 3 parts of a 35 percent soap solution. The creamy liquid that is created in this way dissolves in water to form a permanent one white sulfur emulsion, from which the carbon disulfide can be easily obtained by heating or passing through an inert gas stream. One can also other protective colloids, e.g. B. Sapon: i-n, lysalbi, acidic sodium, etc., add.

Be@ispiel2. i Teil :einer 5oprozentige-n Lösung von Phosphor in Schwefelkohlenstoff wind mit 2 Teilen Türkischrotöl kräftig geschüttelt. Es bildet sich eine milahiggv eiße Flüssigkeit, diie beim Verdünnen mit Wasser (z. B. 2ooo Teilen) .eine .beständige Emulsion .liefert.Be @ ispiel2. i part: a 5% solution of phosphorus in carbon disulfide wind shaken vigorously with 2 parts of Turkish red oil. A milahiggv is formed A very liquid which, when diluted with water (e.g. 2,000 parts), becomes stable Emulsion. Supplies.

Nach dem Austreiben des Schwefelkohlenstoffs .entwickelt die Lösung Dämpfe, die im Dunkeln phosphoreszieren.After the carbon disulfide has been driven off, the solution develops Vapors that phosphoresce in the dark.

Ähnlich kann man bei Verwendung von Selen oder Arsen verfahren.A similar procedure can be used when using selenium or arsenic.
