Zusatz zum Patente 109014 vom 11. Dezember 1898.Addendum to patent 109014 of December 11, 1898.
Patentirt im Deutschen Reiche vom 22. Januar 1899 ab. Längste Dauer: 10. Dezember 1913.Patented in the German Empire on January 22nd, 1899. Longest duration: December 10, 1913.
In Patent 109015 wurde gezeigt, in welcher Weise aus Methan durch Oxydation mit Luft oder Sauerstoff Methylalkohol und Formaldehyd gewonnen werden kann. In ähnlicher Weise reagirt Aethan und bildet bei der Oxydation Aethylalkohol, Acetaldehyd und Essigsäure. Das Verfahren ist dem beim Methan beschriebenen analog.In patent 109015 it was shown in which Way from methane by oxidation with air or oxygen, methyl alcohol and formaldehyde can be won. Ethane reacts in a similar way, and forms on oxidation Ethyl alcohol, acetaldehyde and acetic acid. The procedure is the same as that described for methane analogue.
Man leitet eine Mischung von ungefähr gleichen Raumtheüen Aethan und Luft über eine glühende Contactmasse, die aus Kupfer, Bimsstein, Asbest oder Kupferoxydasbest, jedoch nicht aus Platin oder Platinasbest bestehen darf. Nach dem Passiren der Contactmasse wird das Gasgemisch durch Wasser gewaschen, von Neuem mit dem ungefähr gleichen Volumen Luft gemischt, abermals durch eine Röhre über glühende Contactmasse geleitet, wieder mit Wasser gewaschen und dieser Procefs so oft wiederholt, bis das Gas an Aethan erschöpft ist. Zu den Röhren, in welchen die Reactionswärme nicht ausreicht, die Contactmasse im Glühen zu erhalten, mufs von aufsen Wärme zugeführt werden. Aus den Waschwässern werden auf bekannte Weise die Reactionsproducte Aethylalkohol, Acetaldehyd und Essigsäure genommen. Auch, bei Aethan ist hervorzuheben, dafs bei Anwendung von Platin als Contactmasse aufser Kohlensäure und Wasser keine Oxydationsproducte erhalten werden.A mixture of approximately equal room units of ethane and air is passed over one glowing contact mass made from copper, pumice stone, asbestos or copper oxide asbestos, however may not consist of platinum or platinum asbestos. After passing the contact mass the gas mixture is washed by water, again with approximately the same volume Air mixed, again passed through a tube over glowing contact mass, washed again with water and this procesf repeated until the gas of ethane is exhausted. To the tubes in which the Reaction heat is not sufficient to maintain the contact mass in the glow, must from the outside Heat can be supplied. The reaction products ethyl alcohol and acetaldehyde are produced in a known manner from the washing water and acetic acid taken. In the case of ethane it should also be emphasized that when using Platinum as a contact mass does not contain any oxidation products other than carbonic acid and water will.
Verwendet man an Stelle reinen Aethans äthanhaltige Gasgemische, so arbeitet man in derselben Weise. Der beigemengte Wasserstoff wird am leichtesten und bei niedrigster Temperatur oxydirt. Zu diesem Zweck kann man in der ersten Röhre Platin als Contactmasse verwenden.If you use ethane-containing gas mixtures instead of pure ethane, you work in same way. The added hydrogen is the lightest and the lowest Temperature oxidized. For this purpose, platinum can be used as a contact mass in the first tube use.
Bei Anwendung concentrirten Sauerstoffs mufs dem Procentgehalt entsprechend die dem Aethan beizumischende Menge geändert werden.If concentrated oxygen is used, the percentage must correspond to the percentage The amount to be mixed in with ethane can be changed.
