PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist ein Verfahren zur Entwässerung von Alkoholen, welches im Wesen darin besteht, daß das Wasser den Alkoholen durch metallisches Calcium entzogen wird. Das Verfahren ist sowohl zur Erzeugung von gewöhnlichem »absolutem Alkohol« als auch besonders zur Erzeugung von ganz wasserfreiem Äthylalkohol geeignet. Das Verfahren wird derart ausgeführt, daß der 94 bis 96prozentige Alkohol mit der nötigen Menge Calcium erst erwärmt, dann destilliert wird. Das metallische Calcium wird in Form von Spänen angewendet. Die Behandlung mit Calcium kann auch wiederholt werden. Der so gewonnene Alkohol würde infolge des Nitridgehaltes des metallischen Calciums Ammoniak bezw. dessen Derivate enthalten; um diese zu umgehen, wird das erhaltene Produkt auch noch in bekannter Weise mit Säuren oder sauer reagierenden Salzen behandelt. Vorzugsweise wird dies so ausgeführt, daß der Alkoholdampf bei der Destillation durch gebrannten Alaun geleitet wird.The present invention is a process for the dehydration of alcohols, which essentially consists in the fact that the water is withdrawn from the alcohols by metallic calcium. The procedure is both for the production of ordinary "absolute alcohol" and especially for Production of completely anhydrous ethyl alcohol suitable. The procedure is like this stated that the 94 to 96 percent alcohol with the necessary amount of calcium only heated, then distilled. The metallic calcium is used in the form of chips. Treatment with calcium can also be repeated. The alcohol obtained in this way would be due to the nitride content the metallic calcium ammonia respectively. its derivatives contain; in order to circumvent this, the product obtained also treated in a known manner with acids or acidic salts. Preferably this is done so that the alcohol vapor through the distillation burnt alum is passed.
Als praktisches Beispiel diene folgender Fall: Es soll aus käuflichem, hochgradigem (94 bis 96 prozentigem) Weingeist absoluter Alkohol dargestellt werden. In diesem Falle wird der Weingeist mit etwa ς Prozent Calciumspänen einige Stunden lang erwärmt, dann destilliert; auf diese Weise erhält man als Destillat absoluten Alkohol von 99,0 bis 99,5 Alkoholgehalt. Um vollständig wasserfreien Alkohol zu gewinnen, wird die Operation mit etwa 2 Prozent Calcium ^wiederholt. Das Verfahren kann auch bei anderen Alkoholen angewendet werden.The following case serves as a practical example: It is supposed to be from a commercial, high-grade (94 to 96 percent) alcohol can be represented as absolute alcohol. In this case the alcohol is heated with about ς percent calcium shavings for a few hours, then distilled; In this way, an absolute alcohol of 99.0 to is obtained as the distillate 99.5 alcohol content. To obtain completely anhydrous alcohol, surgery is required with about 2 percent calcium ^ repeated. The procedure can also apply to others Alcohols are used.
