Zusatz zum Patente JVi 83454 vom 15. Januar 1895.Addendum to patent JVi 83454 of January 15, 1895.
Fatentirt im Deutschen Reiche vom 1. Februar i8g6 ab. Längste Dauer: 14. Januar 1910.Fatentirt in the German Empire from February 1st, 18/6. Longest duration: January 14, 1910.
Nach dem durch D. R. P. Nr. 83454 geschützten Verfahren erhält -man Rhodansalze dadurch, dafs man Schwefelkohlenstoff mit Ammoniak und den entsprechenden schwefligsauren oder unterschwefligsauren Salzen der Base, deren Rhodanid man darstellen will, auf einander einwirken läfst. Man kann nach dem Haupt-Patente dieses Verfahren auch in der Weise ausführen, dafs man an Stelle der betreffenden schwefligsaaren oder unterschwefligsauren Salze die freien Basen, dafür aber statt des Ammoniaks eine äquivalente Menge schwefligsaures oder unterschwefligsaures Ammoniak benutzt. Hierdurch wird, wie auch im Haupt-Patente angegeben, der gleiche Erfolg erzielt, da letztere Salze sofort durch die betreffenden Basen zersetzt werden.According to the process protected by D. R. P. No. 83454, rhodan salts are obtained by mixing carbon disulfide with ammonia and the corresponding sulphurous acids or hyposulphurous salts of the base, the rhodanide of which is to be prepared allow each other to act. According to the main patents, this process can also be found in the In the manner of doing this, instead of the sulphurous or hyposulphurous acids in question Salt the free bases, but instead of the ammonia, use an equivalent amount Sulfuric or hyposulphurous ammonia is used. This will, as well stated in the main patents, the same success achieved, since the latter salts immediately through the concerned Bases are decomposed.
Nach vorliegender Erfindung kann man nun an Stelle dieser freien Basen auch die Sulfide (auch Polysulfide, welche nur mehr Schwefel ergeben als die einfachen Sulfide) oder Hydrosulfide derselben anwenden, wenn man saures schwefligsaures Ammoniak für die Bildung des Rhodansalzes benutzt. In diesem Falle wird man bei Ersatz der freien Basen durch die entsprechenden. Sulfide die Hälfte des sonst nöthigen neutralen schwefligsauren Ammoniaks durch saures schwefligsaures Ammoniak ersetzen, während man bei Benutzung der Hydrosulfide sämmtliches neutrales schwefligsaures Ammoniak durch saures schwefligsaures Ammoniak ersetzen wird.According to the present invention, sulfides can now be used instead of these free bases (also polysulphides, which only produce more sulfur than the simple sulphides) or hydrosulphides apply the same if acid sulphurous ammonia is used for the formation of the Rhodan salt used. In this case, if the free bases are replaced by the appropriate. Sulphides make up half of the otherwise necessary neutral sulphurous ammonia Replace with acidic sulphurous ammonia, while using the hydrosulphide all neutral sulphurous ammonia by acid sulphurous ammonia will replace.
