fähigkeitgänzlichvernichtetwird.
Es ist nun bekannt, dass sich diese Nachteile der Harnstoffsuperphosphatgemische, beseitigen lassen, wenn man den iertigen Gemischen oder ihren Bestandteilen alkalisch wirkende Stoffe zusetzt.
Die Erfinderin fand aber, dass sich auch ohne jede besonderen Zusatz fremder StoNe die Hygroskopizität der Harnstoffsuperphosphatgemische und damit ihre nachteiligen Ver- änderungen @eim Lagern beseitigen lassen, wenn man die tertigen Comische erhitzt.
Beispiel I :
Es wurde eine Mischung von 75 Teilen Superphosphat und 25 Teilen Harnstoff in einem Kolben im Glyzerinbad von I60 C I5 NUbyteb kabge ergutzt und nach dem Abkühlen zerkleinert ; die Hygroskopizität war dann verschwunden und das Gemisch blieb dauernd streufähig.
Durch weitere Versuche ist festgestellt werden, dass die gleiche Wirkung auch bei

Process for the preparation of urea superphosphate mixtures.
EMI1.1
ability is completely destroyed.
It is now known that these disadvantages of urea superphosphate mixtures can be eliminated if substances with an alkaline effect are added to the mixtures or their constituents.
The inventor found, however, that even without any special addition of foreign substances, the hygroscopicity of the urea superphosphate mixtures and thus their disadvantageous changes during storage can be eliminated if the tertiary mixtures are heated.
Example I:
A mixture of 75 parts of superphosphate and 25 parts of urea was used in a flask in a glycerine bath at 160 ° C. 15 NUbyteb kabge and, after cooling, comminuted; the hygroscopicity had then disappeared and the mixture remained permanently spreadable.
Through further experiments it can be found that the same effect also occurs
