Verfahren zum Trocknen von Lackleder oder dgl.
Bei der Lackledertrockuung ist es bekannt, das ofentrockene Leder zwecks weiterer Trocknung der gleichzeitigen Einwirkung von zweckmässig ultraviolettem Licht und Ammoniakdämpfen auszusetzen. Dieses Verfahren wird praktisch in der Weise durchgeführt, dass man in den mit Luft gefüllten Raum etwas Ammoniak hineinbringt und dann die Belichtung des Leders vornimmt. Die hiebei erreichte erhöhte Klebsicherheit des Lackleders führte man auf eine Neutralisation der bei der Oxydation auftretenden sauren Anteile der Lacksubstanz zurück.
Weitere Versuche haben nun gezeigt, dass das Ammoniak bei der Belichtung auch als Endprodukt in Stickstoff und Wasserstoff gespalten wird. Dieser Abbau vollzieht sich jedoch über Zwischenprodukte (Hydrazin), weshalb auch diese wie die stärker basisch wirkenden substituierten Ammoniake besonders günstig für die Zwecke der Lackledertrocknung nutzbar gemacht werden können. Das die Trocknung bekanntlich ungünstig beeinflussende Ozon, das bei der Belichtung infolge der Gegenwart von Luft in dem Trockenraum gebildet wird, setzt sich mit dem aus den Derivaten des Ammoniaks abgespaltenen Wasserstoff in statu nascendi in Wasser und Sauerstoff um und verschwindet vollkommen.

Method for drying patent leather or the like.
In patent leather drying, it is known to expose the oven-dry leather to the simultaneous action of suitably ultraviolet light and ammonia vapors for the purpose of further drying. This procedure is practically carried out in such a way that one brings some ammonia into the air-filled space and then exposes the leather. The increased adhesion of the patent leather achieved here was attributed to a neutralization of the acidic components of the lacquer substance that occurred during the oxidation.
Further tests have now shown that the ammonia is split into nitrogen and hydrogen as the end product during exposure. However, this degradation takes place via intermediate products (hydrazine), which is why these, like the more alkaline substituted ammonia, can be used particularly favorably for the purposes of drying patent leather. The ozone, which is known to have an adverse effect on drying and which is formed during exposure as a result of the presence of air in the drying room, reacts with the hydrogen split off from the ammonia derivatives in statu nascendi into water and oxygen and disappears completely.
