   Die Kohlendestillationsgase enthalten fast stets Schwefelwasserstoff. In solchen Fällen erhält man unreine Ammoniumnitratlösungen, wenn man die Gase mit Alkalinitratlaugen behandelt. Man muss in solchen Fällen den Schwefelwasserstoff zuerst aus dem Gase   ent-   fernen, oder man absorbiert das Ammoniak und die Kohlensäure in einer Lauge, welche Schwefelwasserstoff nicht   aufnimmt. Sehr   geeignet dazu sind Magnesiasalzlaugen, z. B. Chlormagnesia, weiche dabei   Magnpsiakarbonat   und   Chlorammonium   bilden. Heim   Abkochen   dieser Laugen erhält man Kohlensäure und Ammoniak, während Chlormagnesium zurückgebildet wird. Um die zur   Ausführung dos   vorliegenden Verfahrens nötige Verdünnung

 Lange.

   Die Verdünnung muss so stark sein, dass sich kein kohlensaures Ammonium in den Gasleitungen absetzen kann.

   The coal distillation gases almost always contain hydrogen sulfide. In such cases, impure ammonium nitrate solutions are obtained if the gases are treated with alkaline nitrate liquors. In such cases the hydrogen sulphide must first be removed from the gas, or the ammonia and carbonic acid can be absorbed in a lye which does not absorb hydrogen sulphide. Magnesia brine, z. B. chloromagnesia, soft thereby forming magnpsia carbonate and chlorammonium. By boiling these alkalis you get carbonic acid and ammonia, while chlorine magnesium is reduced. To obtain the dilution required to carry out the present process
 EMI2.1
 Long.

   The dilution must be so strong that no carbonate of ammonium can settle in the gas lines.
