Description

Verfahren zum Unentflammbarmachen brennbarer Stoffe Es wurde gefunden, claß man brennbare Stoffe dadurch unentflammbar machen kann, daß man sie mit Aniliden der phosphorigen oder Phosphorsäure oder deren Derivaten, wie z. B. Halogenverbindungen, behandelt. Der große Vorteil dieses Verfahrens besteht darin, daß bei der Behandlung mit diesen Stoffen die Ware nicht mit Wasser in Berührung kommt, cla die Stoffe in Form ihrer Lösungen in organischen Lösungsmitteln verwendet werden können.Process for rendering combustible substances non-flammable It has been found that combustible materials can be made non-flammable by adding anilides to them the phosphorous or phosphoric acid or their derivatives, such as. B. halogen compounds, treated. The great advantage of this procedure is that in the treatment with these substances the goods do not come into contact with water, cla the substances can be used in the form of their solutions in organic solvents.

Es wurden bereits Anilidphosphorsäureester als Kampferersatzmittel für die Herstellung von Celluloid empfohlen. Die erhaltenen Produkte sollen nur wenig entflammbar sein; eine Unentflammbarkeit wird durch die Verwendung dieser Anilidphosphorsäureester aber nicht erreicht. Ebensowenig gelingt es, mit diesen Estern z. B. Papier- oder Baumwollumspinnungen von Drähten unbrennbar zu machen. Im Gegensatz hierzu kann man diesen Effekt bei Verwendung der Anilide der phosphorigen oder Phosphorsäure erreichen, wie folgendes Beispiel zeigt.Anilide phosphoric acid esters have already been used as camphor substitutes recommended for the production of celluloid. The products received are intended only be less flammable; one becomes non-flammable by using this Anilidphosphorsäureester but not reached. It is just as unsuccessful with these Esters e.g. B. to make paper or cotton wrapping of wires incombustible. In contrast to this one can get this effect when using the anilides of the phosphorous or phosphoric acid, as the following example shows.

Beispiel Papier- oder baumwollumsponnener Draht wird einige Minuten in eine etwa 5oprozentige Lösung des Trichloranilids der phosphorigen Säure oder des Anilids der Phosphorsäure in Alkohol eingetaucht. Nach Entfernung der überflüssigen Lösung durch Abschleudern und Trocknen ist die Umspinnung unbrennbar.Example paper or cotton braided wire will take a few minutes in an approximately 5% solution of the trichloroanilide of phosphorous acid or of the anilide of phosphoric acid immersed in alcohol. After removing the superfluous Solution by spinning off and drying, the wrapping is non-flammable.
