Description

Herstellung von Kalksalpeter in fester Form. Zusatz zum Patent 429477. Im Hauptpatent ist ein Verfahren zur Gewinnung von festem Kalksalpeter aus seinen Lösungen beschrieben, das darin besteht, diesen zur Erleichterung der 'Kristallisation vor oder nach der Konzentrierung Ammonnitrat zuzufügen.Production of calcium nitrate in solid form. Addendum to patent 429477. In the main patent is a process for the extraction of solid calcium nitrate from his Solutions described, which consists in this to facilitate the 'crystallization add ammonium nitrate before or after concentration.

Es wurde nun gefunden, daß bei diesem Verfahren an Stelle von Ammonnitrat auch solche Stoffe verwendet werden können, die imstande sind, sich mit Kalksalpeter unter Bildung von Ammonnitrat ganz oder teilweise umzusetzen. So kann die gewünschte Wirkung beispielsweise auch durch Zusatz von Ammonsulfat, Ammonsulfatsalpeter, Ammonchlorid usw. erzielt werden. Auch Harnstoff verhält sich unter geeigneten Bedingungen ähnlich. Die Mengen der Zusätze bewegen sich hierbei etwa in ähnlichen Grenzen, wie bei Ammonnitrat angegeben.It has now been found that in this process, instead of ammonium nitrate Also those substances can be used that are able to deal with calcium nitrate to implement in whole or in part with the formation of ammonium nitrate. So can be the one you want Effect, for example, through the addition of ammonium sulphate, ammonium sulphate nitrate, ammonium chloride etc. can be achieved. Urea also behaves similarly under suitable conditions. The amounts of additives are roughly similar to those of ammonium nitrate specified.

Beispiel. Eine Kalksalpeterlösung vom spezifischen Gewicht 1,985 wird bei 13o° mit 5 Prozent ihres Gewichtes an trocknem Chlorammonium versetzt. Die Masse wird hierauf unter Rühren abgekühlt. Sie beginnt bei etwa 9o bis 95' krümelig zu werden, um bei weiterer Abkühlung völlig zu erhärten. Man kann auch hier das feste Salz durch Verspritzen konzentrierter Lösungen erhalten.Example. A calcium nitrate solution with a specific gravity of 1.985 is mixed with 5 percent of its weight of dry chlorammonium at 130 °. The mass is then cooled while stirring. It starts to get crumbly at around 9o to 95 ' to harden completely as it cools down further. Here too, the solid salt can be obtained by spraying concentrated solutions.

Die Verwendung der genannten Salze an Stelle von Ammonnitrat bietet Vorteile, wenn diese Salze neben Kalksalpeter ohnedies hergestellt werden oder leicht erhältlich sind, während für Ammonnitrat eine besondere Fabrikation eingerichtet werden müßte.The use of the salts mentioned in place of ammonium nitrate offers Advantages if these salts are produced anyway in addition to calcium nitrate or lightly are available, while a special production facility has been set up for ammonium nitrate would have to be.

PATENTANSPRUCH: Abänderung des Verfahrens gemäß Patent 429477, dadurch gekennzeichnet, daß den Kalksalpeterlösungen an Stelle von Ammonnitrat andere Ammoniumsalze oder ähnliche Stoffe hinzugefügt werden, die imstande sind, sich mit Kalk-' salpeter unter Bildung von Ammonnitrat umzusetzen. PATENT CLAIM: Modification of the method according to patent 429477, characterized in that instead of ammonium nitrate, other ammonium salts or similar substances are added to the calcium nitrate solutions, which are able to react with calcium nitrate to form ammonium nitrate.
