   Es wurde nun gefunden, dass man eine Doppel verbindung des Kaiksalpeters, welche den   genannten Nachtetl nicht   besitzt und ein vorzügliches Düngemittel darstellt, leicht erhält, wenn man   Kd) lisalpeter   mit Harnstoff bei Gegenwart von Wasser in der Weise   zusammenbringt,   dass sich eine   Doppelverbindung bei der, sei   es ohneweiters oder nach dem Eindampfen, ganz oder der Hauptsache nach ausscheidet. Hiebei bildet sich in weiten Grenzen unabhängig von dem angewandten   MengenverhtUtnis   der Komponenten eine DoppelVerbindung, die auf 1 Molekül Calciumnitrat 4   Moleküle Harnstoff enthält.

Ein längeres und zu hohes erhitzen der Lösungen ist wegen stattfindender Zersetzungen zweckmässig zu vermeiden.

  Process for the production of a fertilizer.
 EMI1.1
 its throwing power is impaired.



   It has now been found that a double compound of Kaiksalpeter, which does not have the aforementioned night and is an excellent fertilizer, is easily obtained if Kd) lisalpeter is brought together with urea in the presence of water in such a way that a double compound is formed in the , be it without further ado or after evaporation, entirely or in the main. In this process, a double compound is formed within a wide range, regardless of the quantitative ratio of the components used, which contains 4 molecules of urea for 1 molecule of calcium nitrate. For their representation you can z.

   B. grind the amount of calcium nitrate corresponding to a molecule in the form of a hydrate with 4 molectiles together and remove the resulting pulp from the mother liquor formed by suction or simply dry the whole thing; A concentrated hot solution of Katksatpotor can also be mixed with a concentrated hot urea solution or with solid urea in suitable quantities, with the new double compound crystallizing out on cooling or even in the strand. It is advisable to avoid prolonged and excessive heating of the solutions due to decomposition.

PATENTANSPRUCH : 1. Verfahren zur Herstellung eines Düngemittels, dadurch gekennzeichnet, dass man calciumnitrat mit Harnstoff bei Gegenwart von Wasser in der Weise zusmmmenbringt, dass sich eine Doppelverbindung beider, sei es ohneweiters oder nach dem Eindampfen, ganz oder der Hauptsache nach ausscheidet. EMI1.2 **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: 1. A process for the production of a fertilizer, characterized in that calcium nitrate is brought together with urea in the presence of water in such a way that a double compound of the two, either without further ado or after evaporation, is entirely or mainly eliminated.
