  Verfahren zur Darstellung reiner Doppelverbindungen sulfoxylsaurer Salze mit
Aldehyden. 



   Durch die den Gegenstand des vorliegenden Zusatzpatentes bildende Erfindung soll das Verfahren des Stammpatentes dahin abgeändert bzw. erweitert werden, dass an Stelle von Aldehyden auch solche organische Präparate treten können, welche leicht in normale Aldehyde   übergehen,   wie die polimerisierten Produkte : Paraformaldehyd (CH2 0)   2   Trioxy- 
 EMI1.1 
 Aldehydammoniak   CA13.   CH (OH).   N H2'  
Allo diese Abkömmlinge von Aldehyden geben in entsprechender Menge angewandt nach den in dem Stammpatent angegebenen Verfahren Doppelverbindungen von Aldehyden mit sulfoxylsauren Salzen. 



   Beispiel : 17 Paraformaldehyd, 150 kg Natriumbisulfit 40  Bé, 60 kg Zinkstaub werden zusammen 1 Stunde gekocht, filtriert und im Vakuum zur Trockene verdampft. Es entsteht so ein fast reines   formaldehydsu1foxylsaures   Natrium. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the preparation of pure double compounds containing sulfoxylic acid salts
Aldehydes.



   The invention, which is the subject of the present additional patent, is intended to modify or expand the process of the parent patent so that, instead of aldehydes, organic preparations can also be used which easily convert into normal aldehydes, such as the polymerized products: paraformaldehyde (CH2 0) 2 trioxy
 EMI1.1
 Aldehyde ammonia CA13. CH (OH). N H2 '
Allo these derivatives of aldehydes give double compounds of aldehydes with sulfoxylic acid salts when applied in the corresponding amount according to the process specified in the parent patent.



   Example: 17 paraformaldehyde, 150 kg sodium bisulfite 40 Bé, 60 kg zinc dust are boiled together for 1 hour, filtered and evaporated to dryness in a vacuum. This creates an almost pure formaldehyde-sulfoxylic acid sodium.

PATENT-ANSPRUCH : EMI1.2 sulfoxyisaurer Salze mit Aldehyden nach Patent Nr. 29202, dadurch gekennzeichnet, dass an Stelle gesättigter Aldehyde im Verfahren des Stanunpatentes, solche organische Präparate verwendet werden, welche leicht in normale Aldehyde übergeben oder sich in solche zurückverwandeln lassen. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: EMI1.2 Sulphoxy acid salts with aldehydes according to patent no. 29202, characterized in that instead of saturated aldehydes in the process of the Stanun patent, organic preparations are used which are easily converted into normal aldehydes or can be converted back into such. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
