Description

Verfahren, organische photographische Tankentwickler geruchlos zu erhalten Zusatz zum Patent 597 966 . In dem Patent 597 966 ist.ein Verfahren behandelt; organische photographische Tankentwickler geruchlos zu erhalten. Erfindungsgemäß wurde nun gefunden, daß man die in dem erwähnten Schutzanspruch verwendeten Salze der Fluorwasserstoffsäure und Kieselfluorwasserstoffsäure auch in Kombination mit anderen desinfizierend wirkenden Körpern verwenden kann, und zwar in der Art, daß von den fluorwasserstoffsauren und kieselfluorwasserstofsauren Salzen einerseits und anderen Desinfektionsmitteln andererseits solche Mengen Verwendung finden, die jede für sich zu einer Desinfektion nicht ausreichen würden. Als solche Körper kommen alle bekannten organischen DesinfektionsmitLel in Frage, so beispielsweise Phenole, Nitrophenole und deren Derivate, organische Säuren, wie Benzoesäure, Salicylsäure, deren Salze und Ester, beispielsweise Paraoxybenzoesäureester u. a. m.Process to make organic photographic tank developer odorless received addition to patent 597 966. A method is dealt with in patent 597,966; to keep organic photographic tank developer odorless. According to the invention it has now been found that the salts used in the aforementioned protection claim of hydrofluoric acid and hydrofluoric acid also in combination with other disinfecting bodies can use, in such a way that of the hydrofluoric acid and silicofluoric acid salts on the one hand and other disinfectants on the other hand, such amounts are used that each would not be sufficient for a disinfection. As such bodies come all known organic disinfectants in question, such as phenols, Nitrophenols and their derivatives, organic acids such as benzoic acid, salicylic acid, their salts and esters, for example paraoxybenzoic acid esters and others. m.
