Description

Herstellung von borfluorwasserstoffsaure Salze enthaltenden Präparaten Die Erfindung besteht in der Herstellung von borfluorwasserstoffsaure Salze enthaltenden Präparaten durch Umsetzung von Borsäure mit sauren Fluoriden. Vermengt man trockene fein pulverisierte Borsäure mit trockenen fein pulverisierten sauren Fluoriden, so tritt nach einiger Zeif eine Umsetzung unter äußerlicher Veränderung der Masse ein.. Dieser Vorgang beruht auf der Umsetzung der Borsäure mit sauren Fluoriden zu borfluorwasserstoffsauren Salzen. Die erhaltene Masse kann durch Trocknen, z. B. durch Behandlung mit warmer Luft, zu einem. streufähig-en Präparat umgewandelt werden.Manufacture of preparations containing borofluoric acid salts The invention consists in the preparation of salts containing borofluoric acid salts Preparations by reacting boric acid with acidic fluorides. Mix dry ones finely powdered boric acid with dry finely powdered acidic fluorides, after a few hours there is a conversion with an external change in the mass a .. This process is based on the reaction of boric acid with acidic fluorides to hydrofluoric acid salts. The mass obtained can be dried, e.g. B. by treatment with warm air, to one. converted to spreadable preparation will.

Die vorliegende Erfindung ist als ein. besonders einfacher Weg zur Herstellung von borfluorwasserstoffsaure Salze enthaltenden Präparaten anzusehen. Je nach dem Mischungsverhältnis der Borsäure und der sauren Fluoride erhält man Produkte, die gegebenenfalls die eine oder andere der Komponenten als Verdünnungsmittel der durch die Umsetzung entstehenden borfluorwasserstoffsauren Salze enthält. Zu guten Resultaten gelangt man z. B. bei der Verwendung von 6o Teilen saurem Natriumfluorid und 4o bis 5o Teilen Borsäure, doch kann man die umzusetzenden Mengen auch anders wählen. Die Umsetzung von Borsäure mit flußsauren Salzen in saurer Lösung -ist schon bekannt. Auf diese Weise gelangt man aber nicht ohne weiteres zu trockenen borfluorwasserstoffsa.uren Salzen, vielmehr bedarf es erst der Entfernung der überschüssigen Säure. Im Gegensatz hierzu ermöglicht das Verfahren. der vorliegenden Erfindung in einfachster Weise die Herstellung trockener borfluorwasserstoffsaurer Salze. Daß sich trockene Borsäure mit trockenen sauren Fluoriden ohne Zusetzung eines Lösungsmittels # umsetzen. würde, war nicht vorauszusehen.The present invention is as a. particularly easy way to Consider the manufacture of preparations containing borofluoric acid salts. Depending on the mixing ratio of the boric acid and the acidic fluoride, one obtains Products that optionally contain one or the other of the components as a diluent of the hydrofluoric acid salts formed by the reaction. to good results can be obtained e.g. B. when using 6o parts of acidic sodium fluoride and 40 to 50 parts of boric acid, but the amounts to be converted can also be different Select. The conversion of boric acid with hydrofluoric acid salts in acidic solution is already possible known. However, dry borofluoric acids are not readily obtained in this way Salts, but the excess acid must first be removed. In contrast the procedure enables this. of the present invention in the simplest way the production of dry borofluoric acid salts. That dry boric acid React with dry acidic fluorides without adding a solvent #. would, was not to be foreseen.

Die nach dem neuen Verfahren hergestellten Präparate können vor allem zu Konservierungszwecken aller Art Verwendung finden.The preparations produced by the new process can above all can be used for preservation purposes of all kinds.
