Das nach vorliegendem Verfahren erhaltene Monozinkformaldehydsulfoxylat lässt sich in manchen Fällen wegen seiner Wasserlöslichkeit mit Vorteil an Stelle des schwerlös- lichen Zinksalzes verwenden.

Anise. 1), a sparingly soluble powder, which is known under the name. If, on the other hand, one vaporizes solutions which contain the monozinc salt corresponding to the usual sodium formaldehyde sulfoxylate, a viscous syrup is obtained, regardless of whether this zinc salt was in solution alone or together with some other salts, such as formaldehyde zinc bisulfite Upon discovery, it solidified to a glassy mass.
It has now been found that this Monozincformaldehydsnlfoxylat can be obtained from its aqueous solutions in crystals, if the solutions are best

<Desc / Clms Page number 2>
Use monozinc salt obtained from the sparingly soluble zinc salt by adding the appropriate amount of acid or from the sodium formaldehyde sulfoxylate by reacting it with a zinc salt in an aqueous solution, whereupon the evaporation either, as when using zinc sulfate, first precipitates the sparingly soluble sodium sulfate, which is removed or, as when using zinc chloride, the monozinc formaldehyde sulfoxylate is obtained straight away.
The monozinc formaldehyde sulfoxylate obtained by the present process can in some cases be used with advantage instead of the sparingly soluble zinc salt because of its water solubility.
