Description
Verfahren zur Herstellung von Goldschwefel. Die Herstellung von technischem Goldschwefel aus Lösungen von Schlippeschem Salz erfolgt durch Behandeln dieser Lösungen mit Mineralsäuren. Die so entstehenden Goldschwefel haben indessen eine mangelhafte Deckkraft und können auch nur schwer säurefrei gewaschen werden, so daß zurückbleibende Säurereste ihnen die Hitzebeständigkeit nehmen und sie dadurch zur Verwendung als Farbstoff in der Gummiwarenfabrikation unbrauchbar machen.Process for the production of gold sulfur. The manufacture of technical Gold sulfur from solutions of Schlippe's salt is made by treating them Solutions with mineral acids. The gold sulfur thus produced, however, has one insufficient coverage and difficult to wash acid-free, like this that remaining acid residues take away their heat resistance and thereby render useless for use as a dye in rubber goods manufacture.
Es wurde nun gefunden, daß sich von diesen Mängeln freie schwefelhaltige Goldschwefel in guter Ausbeute gewinnen lassen, wenn die Ausfällung aus erhitzten Lösungen von Schlippeschem Salz durch ein Gemisch aus Kohlensäure und Sauerstoff unter Druck bewirkt wird. Die Ausfällung des Antimonsulfids selbst erfolgt durch die Kohlensäure, der gleichzeitig eingeleitete Sauerstoff zersetzt den frei werdenden Schwefelwasserstoff zu Schwefel.It has now been found that sulfur-containing free from these defects Let gold sulfur recover in good yield when the precipitate is heated off Solutions of Schlippe's salt by a mixture of carbonic acid and oxygen is effected under pressure. The precipitation of the antimony sulfide itself takes place through the carbonic acid, the oxygen introduced at the same time, decomposes the released Hydrogen sulfide to sulfur.
Die Bildung von rotem Antimonsulfid aus Schlippescher Lösung durch freie Kohlensäure bei gewöhnlichem Druck ist zwar bekannt. Sie verläuft indessen langsam und unvollständig.The formation of red antimony sulphide from Schlippe's solution Free carbon dioxide at normal pressure is known. In the meantime, it is running slow and incomplete.
