Description

Konservierungsmittel Die Eignung von Fluoriden zu Konservierungszwecken ist schon lange bekannt. Es war auch schon erkannt worden, daß die sauren Fluoride für diesen Verwendungszweck vorteilhafte Eigenschaften gegenüber den neutralen Fluoriden besitzen, doch ist die Verwendungsmöglichkeit der sauren Fluoride beschränkt, denn für viele Zwecke sind die starken Säurewirkungen der sauren Fluoride unerwünscht, z. B. bei der Konservierung empfindlicher Häute.Preservatives The suitability of fluorides for preservation purposes has been known for a long time. It had also already been recognized that the acid fluoride for this purpose advantageous properties compared to the neutral fluorides own, but the possible uses of acidic fluorides are limited because for many purposes the strong acidic effects of acidic fluorides are undesirable, z. B. in the preservation of sensitive skins.

Es ist auch bekannt, die Säurewirkungen der.sauren Fluaride durch den Zusatz von Borsäure abzuschwächen. Aus Borsäure und sauren Fluoriden kann man aber keine haltbaren und beständigen Präparate herstellen, denn kurz nach der Vermischung der beiden Bestandteile tritt eine Verflüssigung wahrscheinlich unter Bildung komplexer Borfluoride ein.It is also known to cause the acidic effects of acidic fluarides to weaken the addition of boric acid. Boric acid and acid fluorides can be used but do not make durable and permanent preparations, because shortly after mixing Liquefaction of the two constituents is likely to occur with the formation of complexes Boron fluoride.

Erfindungsgemäß wird nun ein haltbares, Borsäure und saure Fluoride enthaltendes Präparat, das sich vorzüglich für Konservierungszwecke eignet, dadurch hergestellt, daß man den sauren Fluoriden teilweise von ihrem Konstitutionswasser befreite Borsäure zumischt. Infolge des herabgesetzten Wassergehalts der teilweise entwässerten Borsäure vermögen die Komponenten im trockenen Zustand nicht mehr miteinander zu reagieren, sondern nur nach Auflösung im Wasser. Das durch Vermischen der sauren Fluoride und der teilweise entwässerten Borsäure erhaltene Präparat ist unbeschränkt haltbar und die aus diesem Präparat gewonnenen Lösungen als Desinfektionsmittel von empfindlichen, vor allzu starker Säureeinwirkung zu bewahrenden Körpern sehr geeignet. Außer für die Konservierung von Häuten kommt das neue Desinfektionsmittel auch für zahlreiche andere naheliegende Zwecke in Betracht, wie z. B. für die Holzkonservierung, die Konservierung von empfindlichen Textilien und verwandten Stoffen.According to the invention is now a durable, boric acid and acidic fluoride containing preparation, which is particularly suitable for preservation purposes, thereby produced that one of the acid fluorides partially from their constitution water freed boric acid admixed. As a result of the reduced water content of the partially After dehydrated boric acid, the components are no longer able to interact with one another in the dry state to react, but only after dissolving in the water. That by mixing the sour Fluoride and the partially dehydrated boric acid preparation is unlimited durable and the solutions obtained from this preparation as disinfectants of sensitive bodies that have to be protected from excessive acid exposure suitable. In addition to the preservation of hides, there is a new disinfectant also for numerous other obvious purposes into consideration, such as. B. for wood preservation, the preservation of sensitive textiles and related substances.

Als technisch ganz besonders vorteilhaft hat es sich erwiesen, wenn man die Borsäure bis zur Überführung in Metaborsäure entwässert und dann die Metaborsäure mit den sauren Fluoriden vermischt. Die unbeschränkte Haltbarkeit der aus teilweise entwässerter Borsäure und sauren Fluoriden bestehenden' Trockenpräparate war nicht vorauszusehen. Von Borsäureanhydrid war es bekannt, daß es erst bei höheren Temperaturen mit sauren Fluoriden reagiert, bei teilweise entwässerter Borsäure, z. B. Metaborsäure, war aber zu vermuten, daß diese sich sofort unter Verflüssigung mit den sauren Fluoriden umsetzen würde, wie dies bei der Orthoborsäure der Fall ist.It has proven to be particularly advantageous from a technical point of view if the boric acid is dehydrated until it is converted into metaboric acid and then the metaboric acid mixed with the acidic fluorides. The unlimited shelf life of the partially dehydrated boric acid and acid fluorides existing 'dry preparations was not to foresee. It was known of boric anhydride that it only became effective at higher temperatures reacts with acidic fluorides, with partially dehydrated boric acid, e.g. B. metaboric acid, but it was to be assumed that this liquefied immediately with the acidic Fluorides would implement, as is the case with orthoboric acid.

Die folgenden Beispiele beziehen sich auf Konservierungsmittel, die sämtlich aus sauren Fluoriden und verschieden stark entwässerten Borsäuren bestehen. Sowohl die Fluoride wie das Mischungsverhältnis und der Entwässerungsgrad sind in den verschiedenen Beispielen voneinander abweichend. Sämtliche Produkte sind aber im Trockenzustand unbeschränkt haltbare Konservierungsmittel.The following examples relate to preservatives that all consist of acidic fluorides and boric acids with different degrees of dehydration. Both the fluoride, the mixing ratio and the degree of drainage are in the different examples differ from each other. But all products are Preservatives with an unlimited shelf life when dry.

Beispiel i Konservierungsmittel, bestehend aus 6o g Natriumbifluorid und 4o g einer Borsäure, bei der auf je i Mol Borsäure i/2 Mo1 Wasser durch Entwässerung entfernt ist. Beispiel z 6o g Natriumbifluorid und 30 g einer Bors 'iure, bei der auf je i Mol Borsäure 1/2 Mo1. Wasser durch Entwasserwig entfernt ist. Beispiel 3 6o g Kaliuinbifiuorid und 40- einer Borsäure, bei der auf je i Mol Borsäure l/2 11M1 Wasser durch Entwässerung eiitferiit ist.Example i Preservative, consisting of 60 g of sodium bifluoride and 40 g of a boric acid, in which ½ mol of water is removed by dehydration for every 1 mol of boric acid. Example z 60 g of sodium bifluoride and 30 g of a boric acid in which 1/2 mole per 1 mole of boric acid. Water is removed by Entwasserwig. EXAMPLE 3 60 g of potassium bifluoride and 40 g of a boric acid in which for every 1 mole of boric acid 1/2 11 M 1 of water is obtained by dehydration.
