Description

Verfahren zur Darstellung von gelbem Schwefelantimon. Gelbes Schwefelantimon (Goldschwefel) wurde bisher durch Fällen von Schlippeschem Salz (Na" Sb S4) mit Säuren erhalten. Hierbei wird das in diesem Salz enthaltene Schwefelnatrium ungenützt unter Entwicklung von Schwefelwasserstoff, der ein unangenehmes Nebenprodukt darstellt, zersetzt.Process for the preparation of yellow sulfur antimony. Yellow sulfur antimony (Gold sulfur) was previously obtained by precipitating Schlippe's salt (Na "Sb S4) with Acids obtained. The sodium sulphide contained in this salt is unused with the development of hydrogen sulfide, which is an unpleasant by-product, decomposed.

Es wurde nun gefunden, daß sich unter Vermeidung dieses Übelstandes gelbes Schwefelantimon durch Umsetzung von Natriumsulfantimoniat (Schlippesches - Salz) mit Polythionaten gewinnen läßt, wobei das Polythionat gleichzeitig in. Thiosulfat übergeführt wird. Die Reaktionen finden beispielsweise nach folgenden Gleichungen statt: 2 Nag Sb S4 + 3 Nag S, O, - Sb-. S, -f- 6 Nag S, 0g; 2NagSbS4 + 3Na2S40r - Sbz Sr, + 6 Nag S2 03 -f- 3 S. Bei Verwendung höher geschwefelter Polythioihverbindungen als Trithionat enthält das Produkt freien Schwefel.It has now been found that, while avoiding this inconvenience yellow sulfur antimony by converting sodium sulfantimoniate (Schlippesches - Salt) can be obtained with polythionates, the polythionate at the same time in. Thiosulfate is transferred. The reactions take place, for example, according to the following Equations instead: 2 Nag Sb S4 + 3 Nag S, O, - Sb-. S, -f- 6 Nag S, 0g; 2NagSbS4 + 3Na2S40r - Sbz Sr, + 6 Nag S2 03 -f- 3 S. When using higher sulfur polythioic compounds the product contains free sulfur as trithionate.

Das Verfahren hat den Vorteil, daß die Schwefelwasserstoffentwicklung vollständig vermieden wird, und die bei anderweitigen technischen Prozessen abfallenden Polythionatlösungen unter Gewinnung des wertvolle= ren-Thiosulfats Verwendung finden können.The process has the advantage that the evolution of hydrogen sulfide is completely avoided, and that which is lost in other technical processes Find polythionate solutions with recovery of the valuable = ren thiosulfate use can.

Beispiel. Zu einer Lösung von i ooo Gewichtsteilen Natriumtrithionat in z ooo Gewichtsteilen Wasser läßt man bei gewöhnlicher Temperatur unter gutem Rühren im Verlauf von q bis 6 Stunden eine Lösung von 1 33o Gewichtsteilen kristallisiertem Schlippeschen Salz in 3 ooo Gewichtsteilen Wasser zulaufen. Man erhält 55o Gewichtsteile Schwefelantimon und z ooo Gewichtsteile Natriumthiosulfat.Example. To a solution of 100 parts by weight of sodium trithionate in zoo parts by weight of water one leaves at ordinary temperature under good Stir for q to 6 hours a solution of 1,330 parts by weight of crystallized Run in Schlippe's salt in 3,000 parts by weight of water. 55o parts by weight are obtained Sulfur antimony and z ooo parts by weight sodium thiosulphate.

Die Umsetzung läßt sich auch in der Wärme ausführen; auch kann man beide Bestandteile gleichzeitig in das Rührgefäß einlaufen lassen.The reaction can also be carried out in the heat; also one can Let both components run into the mixing vessel at the same time.
