  Verfahren zur Gewinnung von Zyan und Ammoniak. 



   In der Patentschrift Nr. 62974 ist ein Verfahren beschrieben zur nahezu quantitativen Ausnutzung des in den Schlempegasen enthaltenen Stickstoffs. In der Natur der dort verwendeten Heizkanäle,   geschmolzener   Quarz oder Zirkonquarz usw., ist es begründet, dass man nur verhältnismässig kleine Heizflächen hat und man ist daher genötigt,   um die   
 EMI1.1 
 Gasgeschwindigkeiten zu arbeiten. Dass trotz dieser verhältnismässig kleinen Gasgeschwindigkeiten hervorragende Stickstoffausbeuten erzielt werden, dafür sind in der genannten 
 EMI1.2 
 zweifellos einen höchst bedentsamen technischen Fortschritt und der einzige   Nachteil.   welcher dem Verfahren anhaftet, ist nur der, dass zur Bewältigung der enormen Gas-

 Anlagen erforderlich sind.

  Process for the extraction of cyan and ammonia.



   Patent specification No. 62974 describes a method for the almost quantitative utilization of the nitrogen contained in the pulp gases. In the nature of the heating channels used there, fused quartz or zirconium quartz, etc., it is justified that one only has relatively small heating surfaces and one is therefore required to use them
 EMI1.1
 Gas velocities to work. The fact that, despite these relatively low gas velocities, excellent nitrogen yields are achieved is explained in the above
 EMI1.2
 undoubtedly a very significant technical advance and the only disadvantage. what is attached to the process is only that to cope with the enormous gas
 EMI1.3
 Facilities are required.



   The results of comparative cyanization experiments in a tube are shown
