Die Ursache der Unbeständigkeit der Wasserstoffsuperoxydverbindungen, wie sie von Tanatar(Chcm.Ccntralblatt, 1908, II, S.583) beschrieben worden sind, ist Gegenstand von Untersuchungen gewesen, ohne daß aber bis jetzt das Wesen dieser Zersetzungsursachen in allen Einzelheiten erkannt worden ist.The cause of the instability of hydrogen peroxide compounds, as described by Tanatar (Chcm.Ccntralblatt, 1908, II, p.583) is the subject of Investigations have been made without, however, as yet investigating the nature of these causes of decomposition has been recognized in every detail.
So hat man anderwärts gefunden, daß man haltbare Produkte erhält, wenn man bei der »o. Herstellung niedrige Temperaturen anwendet oder vor der Abscheidung der Doppelverbin-(iung aus der wässerigen Lösung ihrer Bestandteile geringe Mengen eines anorganischen alkalibindcnden Stoffes von schwach saurem · Charakter hinzusetzt.So it has been found elsewhere that durable products are obtained if one works with the "O. Manufacturing uses low temperatures or prior to the deposition of the double compound (i from the aqueous solution of its constituents small amounts of an inorganic alkali-binding substance of a weakly acidic substance · Add character.
Es wurde nun gefunden, daß man- auch haltbare Wasserstoffsuperox\-dverbindungen erhalten kann, wenn man zu deren Darstellung an Stelle der bisher benutzten hochproao zentigcn Wasserstoffsuperoxydlösung das im Handel leicht zugängliche, etwa 3 prozentige technische Wasserstoffsuperoxyd verwendet und dieses in Mischung mit den zur Festigung ' des Wasserstoffsuperoxyds dienenden anora5 ganischen oder organischen Stoffen vorsichtig, . in Yakmim, eindampft. Dieses Ergebnis ist durchaus ül>crraschend und von großer technischer Bedeutung, da die schwierige und verlustreiche Reinigung und Konzentration der Wasscrstoffsupcroxydiösung wegfällt.It has now been found that durable hydrogen peroxide compounds can also be obtained if, instead of the previously used high percentage hydrogen peroxide solution, the readily available commercially available approximately 3% technical hydrogen peroxide is used for their preparation and this is mixed with the solidification 'of hydrogen peroxide serving anor a 5 ganic or organic substances careful. in yakmim, evaporated. This result is quite surprising and of great technical importance, since the difficult and lossy cleaning and concentration of the hydrogen superoxide solution is no longer necessary.
In der amerikanischen Patentschrift 970898 ist die Verwendung· von iogrädigcm Wasserstoffsupcroxyd erwähnt. Es sind aber darin keinerlei Angaben über den Reinheitsgrad oder die Haltbarkeit des verwendeten Wasserstoffsuperoxyds enthalten. Die Tatsache, daß nach der Patentschrift flic Doppclverbindung aus Wasserstoffsuperoxyd und KNOn von der Lauge getrennt werden muß, läßt nicht den Schluß zu, daß es möglich ist, auch beim Abdampfen im guten \'akmini eine haltbare, Doppelvcrbindung1· ohne Zersetzung und in quantitativer Ausbeute zu gewinnen, wie es das Verfahren vorliegender Erfindung gestattet. In the American patent 970898 the use of iogradigcm hydrogen is mentioned stoffsupcroxyd. However, it does not contain any information about the degree of purity or the shelf life of the hydrogen peroxide used. The fact that n after the patent flic Doppclverbindung from hydrogen peroxide and KNO must be separated from the lye, does not allow the conclusion that it is possible akmini also on evaporation in good \ 'a durable, Doppelvcrbindung 1 × without decomposition and To gain quantitative yield, as the process of the present invention allows.
6o Teile Harnstoff werden mit 1500 Teilen 3 prozentiger käuflicher Wa.sserstoffsupcroxydlösung im Vakuum eingedampft und gctrocknet. Die farblose, nicht hygroskopische Kristallmassc wird in fast theoretischer Ausbeute erhalten und besitzt einen Gehalt von 35 bis 36 Prozent H, O2.60 parts of urea are evaporated in vacuo with 1500 parts of 3 percent commercially available wa.sserstoffsupcroxydlösung and dried. The colorless, non-hygroscopic crystal mass is obtained in almost theoretical yield and has a content of 35 to 36 percent H, O 2 .
