Die Umsetzung von Erdalkalisulfiden mit Ammoniumsalzen ■ zur Gewinnung von Salzen der Erdalkalimetalle hat man bisher in wäßriger Suspension oder Lösung oder durch Behandlung des trockenen Gemisches mit Dampf zu bewirken gesucht. In den beiden ersten Fällen treten Schwierigkeiten dadurch auf, daß die Erdalkalisulfide entweder zum Teil nicht im Wasser gelöst sind oder beim Lösen inThe conversion of alkaline earth metal sulfides with ammonium salts ■ for the production of salts the alkaline earth metals have hitherto been obtained in aqueous suspension or solution or by treatment sought to effect the dry mixture with steam. In the first two cases, difficulties arise in that the alkaline earth sulfides are either partly not dissolved in water or when dissolving in

to Wasser Verbindungen, wie Ba(OH)2 · Ba(SH)2, bilden, die sich der Reaktion entziehen.to water compounds such as Ba (OH) 2 · Ba (SH) 2 , which evade the reaction.

Es hat sich nun überraschenderweise gezeigt, daß man die Erdalkalisulfide leicht in Erdalkalimetallsalze umwandeln kann, wenn man sie mit Ammoniumsalzen vermahlt. Um die Reaktion zu beschleunigen, spritzt man zweckmäßig geringe Mengen Wasser während des Vermahlens auf die Mischung. Die Umsetzung verläuft nahezu quantitativ; im allgemeinen treten mehr als 98 % des als Sulfid gebundenen Schwefels in Reaktion. Durch Heizen des Kollerganges kann man die Reaktion noch weiter beschleunigen. Die entweichenden Schwefelammoniumverbindungen können z. B. unter Rückgewinnung des Ammoniaks in bekannter Weise aufgearbeitet werden.It has now been shown, surprisingly, that the alkaline earth sulfides can easily be converted into alkaline earth metal salts can convert if you grind them with ammonium salts. In order to accelerate the reaction, it is advisable to spray small amounts of water while grinding on the mixture. The implementation is almost quantitative; in general more than 98% of the sulfur bound as sulphide reacts. By heating the The reaction can be accelerated even further. The escaping sulfur ammonium compounds can e.g. B. be worked up in a known manner with recovery of the ammonia.

moniumnitrat vermählen, wobei nach und nach 7 1 Wasser aufgespritzt werden; das erhaltene rohe Bariumnitrat ist frei von Sulfidschwefel.grind monium nitrate, gradually spraying 7 liters of water; the received raw barium nitrate is free from sulfide sulfur.

Beispiel 2Example 2

179 kg Strontiumsulfid mit einem Gehalt von 119,6 kg SrS werden mit 107 kg Chlorammonium auf dem Kollergang vermählen; dabei wird Wasser aufgespritzt. Man erhält Strontiumchlorid in vorzüglicher Ausbeute.179 kg of strontium sulfide with a content of 119.6 kg of SrS are mixed with 107 kg of chlorammonium grind on the pan mill; water is sprayed on in the process. You get Strontium chloride in excellent yield.

Beispiel 3Example 3

103,6 kg Schwefelcalcium und 160 kg Ammoniumnitrat werden innig vermählen; die Umsetzung kann ohne Zusatz von Wasser durchgeführt werden. Calciumnitrat wird in guter Ausbeute erhalten.103.6 kg of calcium sulfur and 160 kg of ammonium nitrate are intimately married; the reaction can be carried out without the addition of water will. Calcium nitrate is obtained in good yield.

In entprechender Weise verfährt man bei der Herstellung wasserunlöslicher Erdalkalimetallsalze. A corresponding procedure is used in the production of water-insoluble alkaline earth metal salts.
