von Alkohol haltbar zu machen.to preserve from alcohol.
Patentiert im Deutschen Reiche vom 13. September 1910 ab.Patented in the German Empire on September 13, 1910.
Dem Wasserstoffsuperoxyd, einem in vieler Beziehung idealen Oxydationsmittel, haftet der schwerwiegende Nachteil an, daß es in ständiger Zersetzung begriffen ist. Der Gehalt einer Wasserstoffsuperoxydlösung an aktivem Sauerstoff nimmt beständig ab, derart, daß beispielsweise ein technisches Wasserstoffsuperoxyd mit 3,o Gewichtsprozent H2 O2 nach einem Monat nur 2,7 Prozent, nach zwei Monaten 2,4 Prozent und nach drei Monaten 2,1 Prozent H2 O2 enthält.Hydrogen peroxide, an ideal oxidizing agent in many respects, has the grave disadvantage that it is constantly decomposing. The active oxygen content of a hydrogen peroxide solution is constantly decreasing, such that, for example, a technical hydrogen peroxide with 3.0 percent by weight H 2 O 2 only 2.7 percent after one month, 2.4 percent after two months and 2.1 after three months Contains percent H 2 O 2.
Noch viel rascher verläuft die Zersetzung des Wasserstoffsuperoxyds in konzentrierten Lösungen, so daß man bisher gezwungen war, in der Technik Wasserstoffsuperoxydlösungen mit nur 3 Gewichtsprozenten H2 O2 zu verwenden. Zum Haltbarmachen von Wasserstoffsuperoxydlösungen sind eine Anzahl verschiedenartiger Zusätze empfohlen worden, von welchen beispielsweise folgende herausgegriffen werden mögen: Phosphorsäure, Chlornatrium, Stärkekleister (Patentschrift 196700, Kl. 30h), Acylamide (Patentschrift 174190, Kl. 121), Gelatine (Patentschrift 185597, Kl. 121), Gerbsäure (Patentschrift 196370, Kl. 121), Harnsäure (Patentschrift 203019, Kl. 121), Naphtalin, Oxalsäure usw.The decomposition of hydrogen peroxide proceeds much more rapidly in concentrated solutions, so that up to now one has been forced to use hydrogen peroxide solutions with only 3 percent by weight of H 2 O 2 in technology. To preserve hydrogen peroxide solutions, a number of different additives have been recommended, of which, for example, the following may be singled out: phosphoric acid, sodium chloride, starch paste (patent specification 196700, class 30h), acylamides (patent specification 174190, class 121), gelatine (patent specification 185597, class . 121), tannic acid (patent specification 196370, class 121), uric acid (patent specification 203019, class 121), naphthalene, oxalic acid, etc.
Es ist ferner bekannt, daß die Haltbarkeit des technischen 3 prozentigen Wasserstoffsuperoxyds begünstigt wird durch Zusatz von 20 g Alkohol oder Äther auf 11 Flüssigkeit (s. Max Bottier, Bleich- und Detachiermittel der Neuzeit 1908, S. 47).It is also known that the shelf life of technical 3 percent hydrogen peroxide This is beneficial by adding 20 g of alcohol or ether to 11 liquids (see Max Bottier, Bleaching and Spotting Agents of Modern Times 1908, p. 47).
Es wurde nun gefunden, daß, falls man den Alkoholzusatz auf mindestens das 5 fache erhöht, also mindestens 100 g Alkohol auf 1 1 Wasserstoffsuperoxyd zufügt, jede Zersetzung des Wasserstoffsuperoxyds völlig hintangehalten wird. Dieses Verfahren würde allerdings ohne Bedeutung für das bisher gebräuchliche Wasserstoffsuperoxd mit 3 Gewichtsprozent H2O2 sein, da ein Zusatz von 100 g Alkohol auf 30 g H2 O2 den Preis des Wasserstoffsuperoxyds ganz wesentlich verteuern würde. Anders steht aber die Sache, falls es gelingt, auch ein hochprozentiges Wasserstoffsuperoxyd durch Zusatz von 100 g Alkohol pro 1 Liter zu konservieren. Es hat sich nun in der Tat gezeigt, daß ein Wasserstoffsuperoxyd von beispielsweise 30 Gewichtsprozent H% O2 — genügende technische Reinheit dieses Präparates vorausgesetzt — durch einen Zusatz von mindestens 10 Gewichtsprozent Alkohol dauernd konserviert werden kann. Sind in dem zu konservierenden Wasserstoffsuperoxyd größere Mengen die Zersetzung begünstigende Stoffe vorhanden, so empfiehlt es sich, den Alkoholzusatz bis auf 20 bzw. 40 Prozent zu steigern.It has now been found that if the addition of alcohol is increased to at least 5 times, i.e. at least 100 g of alcohol per 1 liter of hydrogen peroxide is added, any decomposition of the hydrogen peroxide is completely prevented. However, this process would be of no importance for the hydrogen peroxide with 3 percent by weight H 2 O 2 , which has been used up to now, since an addition of 100 g of alcohol to 30 g of H 2 O 2 would make the price of the hydrogen peroxide very much more expensive. The situation is different if it is possible to preserve a high-percentage hydrogen peroxide by adding 100 g of alcohol per 1 liter. It has now actually been shown that a hydrogen peroxide of, for example, 30 percent by weight H % O 2 - provided this preparation is of sufficient technical purity - can be permanently preserved by adding at least 10 percent by weight of alcohol. If the hydrogen peroxide to be preserved contains larger quantities of substances that favor decomposition, it is advisable to increase the alcohol addition up to 20 or 40 percent.
Die Beständigkeit eines derartigen alkoholischen Gemisches war keineswegs vorauszusehen,The stability of such an alcoholic mixture could by no means be foreseen,
denn hochkonzentriertes Wasserstoffsuperoxyd ist bekanntlich ein Präparat von außerordentlicher Oxydationskraft, welches viele brennbare Körper.direkt entzündet (s. Abeggs Handbuch der anorganischen Chemie 1908, II. Band, S. 89). Im Gegensatz hierzu hat sich nun gezeigt, daß man konzentriertes Wasserstoffsuperoxyd mit 10 bis 100 Prozent Alkohol gefahrlos mischen kann, daß diese Lösungen gekocht werden können, ohne daß irgendeine Veränderung eintritt, und daß diese Mischungen bei Zimmertemperatur eine unbegrenzte Haltbarkeit besitzen.for highly concentrated hydrogen peroxide is known to be an extraordinary preparation Oxidative power, which directly ignites many combustible bodies (see Abeggs handbook der inorganic Chemie 1908, Volume II, p. 89). In contrast, it has now shown that one can use concentrated hydrogen peroxide with 10 to 100 percent alcohol can mix safely that these solutions can be cooked without any Change occurs, and that these mixtures have an unlimited shelf life at room temperature own.
