Description
Aus Formaldehyd und schwefliger Säure bzw. aus formaldehydschwefliger Säure entsteht bei Erhitzen mit Zinkstaub auf etwa ioo ° bzw. bei mehrtägigem Durchrühren bei gewöhnlicher Temperatur ein schwer lösliches Zinksalz der Formaldehydsulfoxylsäure.Formaldehyde and sulphurous acid or formaldehyde-sulphurous acid are produced when heated with zinc dust to about 100 ° or when stirred for several days at ordinary temperature a sparingly soluble zinc salt of formaldehyde sulfoxylic acid.
Es hat sich nun gezeigt, daß man die Umsetzung so leiten kann, daß als Endprodukt . das leicht lösliche Zinksalz der formaldehydhydroschwefligen Säure entsteht. Dieses erhält man, wenn man die genannten Komponenten unter Kühlung oder bei gewöhnlicher Temperatur bzw. unter Vermeidung stärkeren Erhitzens nur so lange aufeinander einwirken läßt, als noch keine nennenswerte Abscheidung des schwer löslichen' Formaldehydzinksulfoxylats. erfolgt. Die Arbeitsweise der Patente 202825 und 202826 soll hierbei ausgenommen werden.It has now been shown that the reaction can be conducted in such a way that as the end product . the easily soluble zinc salt of formaldehyde hydrosulphurous acid is formed. This gets one, if one of the components mentioned under cooling or with ordinary Temperature or avoiding excessive heating only act on each other for so long leaves, as no significant separation of the sparingly soluble 'formaldehyde zinc sulfoxylate. he follows. The mode of operation of patents 202825 and 202826 is to be excluded here will.
540 Gewichtsteile wässerige formaldehydschweflige Säure (aus 192 Gewichtsteilen S O2 und 90 Gewichtsteilen C H2 0) werden zu 300 Gewichtsteilen Zinkstaub, welcher mit 500 Gewichtsteilen Wasser angepastet ist, zugefügt unter gutem Rühren, welches noch einige Stünden fortgesetzt wird. Alsdann wird filtriert; das ölige Filtrat, welches im Vakuum noch weiter eingedampft werden kann, enthält das Zinksalz der formaldehydhydroschweüigen Säure. Versetzt man die wässerige Lösung desselben mit Sodalösung, so erhält man neben ausfallendem Zinkcarbonat Formaldehydnatriumhydrosulfit; beim Kochen der wässerigen Lösung des genannten Zinksalzes mit Zinkstaub entsteht basisches Zinkformaldehydsulfoxylat.540 parts by weight of aqueous formaldehyde-sulphurous acid (from 192 parts by weight of SO 2 and 90 parts by weight of CH 2 O) are added to 300 parts by weight of zinc dust, which is pasted with 500 parts by weight of water, with thorough stirring, which is continued for a few hours. It is then filtered; the oily filtrate, which can be further evaporated in vacuo, contains the zinc salt of formaldehyde-hydrosulfuric acid. If the aqueous solution of the same is mixed with soda solution, in addition to precipitated zinc carbonate, formaldehyde sodium hydrosulfite is obtained; basic zinc formaldehyde sulfoxylate is formed when the aqueous solution of said zinc salt is boiled with zinc dust.
Zweckmäßig ist es, die Reduktion der schwefligen Säure unter Zusatz von Alkohol vorzunehmen.It is useful to reduce the sulphurous acid with the addition of alcohol to undertake.
