Patentiert im Deutschen Reiche vom 19. April 1908 ab.Patented in the German Empire on April 19, 1908.

Es sind Verfahren bekannt geworden, nach denen es gelingt, in Gegenwart von Metallen Wasserstoff aus organischen Verbindungen mehr oder weniger leicht und glatt abzuspalten oder an geeignete organische Verbindungen Wasserstoff anzulagern. Bei der Untersuchung solcher Reaktionen wurde die Beobachtung gemacht, daß katalytisch wirksame Metalle ihre Wirkung einbüßen können. Es wurdeProcesses have become known which can be used in the presence of metals To split off hydrogen from organic compounds more or less easily and smoothly or to add hydrogen to suitable organic compounds. During the examination Such reactions have been observed to be catalytically active metals can lose their effectiveness. It was

ίο merkwürdigerweise festgestellt, daß die Metalle im Zustande hoher Reinheit weniger wirksam, nicht selten sogar unwirksam sind. Beim weiteren Verfolgen dieser Beobachtung hat es sich gezeigt, daß gewisse Zusätze, besonders von Basen, und vor allem von Alkalien, eine sehr hohe Aktivierung bewirkt. Wenn man z. B. reinem Nickelpulver, das man aus dem Oxyd durch Erhitzen im Wasserstoffstrom dargestellt hat, und das sich beispielsweise gegen Borneol und Isoborneol inaktiv zeigt, geringe Mengen von reinem Natriumhydroxyd einverleibt, so wird das Nickel in' hohem Maße aktiv. Die Aktivität prüft man in der Weise, daß man kleine Mengen des Metalles ζ. B. in einer Lösung von Borneol oder Isoborneol in hochsiedenden Flüssigkeiten wie Paraffinöl oder Petroleum einführt und die in einer gewissen Zeiteinheit entwickelte Wasserstoff menge mißt.ίο strangely found that the metals in a state of high purity are less effective, not infrequently even ineffective. In following this observation further it has been shown that certain additives, especially of bases, and especially of alkalis, causes a very high level of activation. If you z. B. pure nickel powder, which is obtained from the oxide by heating it in a stream of hydrogen has shown, and that is inactive, for example, against borneol and isoborneol shows that small amounts of pure sodium hydroxide are incorporated, the nickel is highly active. The activity is tested in such a way that one small amounts of the Metal ζ. B. in a solution of borneol or isoborneol in high-boiling liquids like paraffin oil or petroleum and which developed in a certain time unit Measure the amount of hydrogen.

Folgende Beispiele mögen die Erfindung erläutern: The following examples illustrate the invention:

1. Reines Nickelnitrat, das ohne weitere Zusätze ein für die Überführung von Borneol in Kampfer ganz inaktives Nickelpulver gibt, wird in wenig Wasser gelöst. Hierauf gibt man 0,14 Prozent verdünnte reine Natronlauge (als Na2 O berechnet) zu. Nach dem Eindampfen der Lösung zur Trockne, Verglühen des Nitrates zu Nickeloxyd und Reduktion des letzteren zu metallischem Nickel, zeigt sich dieses gegen Borneol bzw. Isoborneol stark aktiv, so daß die Überführung, in Kampfer in kurzer Zeit gelingt.1. Pure nickel nitrate, which, without any further additives, is a nickel powder that is completely inactive for the conversion of borneol into camphor, is dissolved in a little water. 0.14 percent diluted pure sodium hydroxide solution ( calculated as Na 2 O ) is then added. After evaporating the solution to dryness, burning the nitrate to nickel oxide and reducing the latter to metallic nickel, this shows itself to be highly active against borneol or isoborneol, so that the conversion into camphor succeeds in a short time.

2. Zu einem inaktiven Nickel, das in schmelzendes Borneol eingetragen war, wird 0,17 Prozent reines Natriumoxyd zugegeben. Sofort tritt lebhafte Wasserstoffentwicklung ein.2. Becomes an inactive nickel that was incorporated into melting borneol 0.17 percent pure sodium oxide was added. Vigorous evolution of hydrogen occurs immediately.
