Description

Verfahren zur Herstellung von Ammonnitratsprengstoffen. Es wurde gefunden, daß man gießbare Ammonnitratsprengstoffe durch Zusatz von Alkalinitrat in molekularem oder annähernd molekularem Verhältnis herstellen kann. Man weiß zwar, daß eine Mischung gleicher Äquivalente von salpetersaurem Kali und Natron bei ?2o' schmilzt, nicht bekannt aber war, daß man durch Zusammenschmelzen von Ammonnitrat mit Alkalinitrat wesentlich nied_iger schmelzende Gemische erhält.Process for the manufacture of ammonium nitrate explosives. It was found, that pourable ammonium nitrate explosives by adding alkali nitrate in molecular or can produce an approximate molecular ratio. You know that it is a mixture equal equivalents of nitric acid potash and soda at? 2o 'does not melt it was known, however, that one can fuse ammonium nitrate with alkali nitrate Much lower-melting mixtures are obtained.

Beispiel: Zwei Teile Ammonnitrat und zwei Teile Natriumnitrat werden auf r2o ° erhitzt, man kann die Masse dann gießen. Sie erstarrt beim Erkalten zu einer harten Masse. Man kann den Schmelzpunkt noch weiter erniedrigen, indem man Gemische von Alkalinitraten oder organische Stoffe, insbesondere Salze und Amide der Fettsäuren zusetzt. Z. B. zwei Teile Ammonnitrat, zwei Teile Natriumnitrat, ein Teil Acetamid werden erhitzt, bis das Gemisch gießbar wird, was bei ungefähr 6o' eintritt. Nach dem Erkalten ist die Masse plastisch.Example: Two parts of ammonium nitrate and two parts of sodium nitrate are used heated to r2o °, you can then pour the mass. It freezes when it cools down a hard mass. You can lower the melting point even further by Mixtures of alkali nitrates or organic substances, especially salts and amides which adds fatty acids. E.g. two parts ammonium nitrate, two parts sodium nitrate, a part of acetamide is heated until the mixture becomes pourable, which is about 6o 'entry. After cooling, the mass is plastic.

Bei Zusatz von verschiedenen Alkalinitr aten oder von Fettsäuren oder Oxyfettsäuren oder von Salzen oder Amiden dieser Säuren, der aromatischen Oxysäuren oder Sulfosäuren oder von ätherschwefelsauren Salzen oder Dioxybenzolen oder Gemischen dieser Stoffe ist man nicht an molekulare Verhältnisse zwischen Ammon- und Alkalinitrat gebunden, wie folgendes Beispiel zeigt Ein Gemisch von vier Teilen Ammonnitrat mit einem Teil Natrilunnitrat ist nach Zusatz von 1l/, Teilen Acetamid bei 55 ° gießbar, nach Zusatz von il/, Teilen Natriumformiat bei 75' und nach Zusatz von 3/4 Teilen Natriumformiat und gleichzeitig 3/4 Teilen Acetamid bei 6o bis 65 @.When adding various alkali nitrates or fatty acids or oxyfatty acids or salts or amides of these acids, the aromatic oxyacids or sulfonic acids or ethersulfuric acid salts or dioxybenzenes or mixtures of these substances, one is not bound to the molecular ratio between ammonium and alkali nitrate, as the following example shows a mixture of four parts of ammonium nitrate with a part Natrilunnitrat is after addition of 1 l / parts acetamide pourable at 55 °, after addition of il /, parts of sodium at 75 ', and after addition of 3/4 parts of sodium and simultaneously 3/4 Share acetamide at 6o to 65 @.

Auch in der französischen Patentschrift 35037= sind Sprengstoffe b.-schrieben, wclcl:c aus Ammonnitrat und Metallnitraten bestehen. Es werden aber nicht die leicht zugänglichen Nitrate der Alkalien, sondern Blei- und Kupfernitrat angewendet und in solchen Mengenverhältnissen (8o Teile Ammonnitrat zu 30o Teilen Kupfer- und 450 Bleinitrat), daß es sich nicht um das Gießbarmachen von Ammonnitrat durch Metallnitratzusatz, sondern um das Schmelzbarmachen von Kupfer- und Bleinitrat durch einen kleinen Zusatz von Ammonnitrat handelt. Die Schmelzpunkte dieser Mischungen sind viel höher als bei den gießbaren Ammonnitratsprengstoffen.Also in the French patent 35037 = explosives are b.-written, wclcl: c consist of ammonium nitrate and metal nitrates. But it won't be easy accessible nitrates of alkalis, but lead and copper nitrate are applied and in such proportions (8o parts ammonium nitrate to 30o parts copper and 450 parts Lead nitrate) that it is not a matter of making ammonium nitrate pourable by adding metal nitrate, but about making copper and lead nitrate meltable by adding a small amount is about ammonium nitrate. The melting points of these blends are much higher than in the case of pourable ammonium nitrate explosives.
