Description
Verfahren zum Karbonisieren. Den Gegenstand der Erfindung bildet ein Verfahren zum Karbonisieren. Es ist bereits bekannt, daß man Zellulose durch hochkonzentrierte Salzlösungen zur Quellung bringen oder lösen kann (vgl.Patentschrift 275882, Klasse 2g). Aber auch dieser Vorgang geht nur langsam und nur in so geringfügigem Maße vor sich, daß z. B. Herzog und Beck (Zeitschrift für Phys. Chemie 192o, Band 1z, Seite 287) nur einprozentige Watte durch Erhitzen auf 12o bis 13o' während 24 Stunden zum Gelatinieren bringen konnten. Auch wurde schon der Vorschlag gemacht, mittels sehr verdünnter Magnesiumchloridlösung zu karbonisieren, wobei nach dem Trocknen des zu behandelnden Gutes durch längeres Erhitzen (5o bis go Minuten) eine Zersetzung des Chlormagnesiums herbeigeführt und dadurch die vorhandene Zellulose zerstört wird. Dieses Verfahren ist ziemlich umständlich durchzuführen und erfordert ebenfalls geraume Zeit.Carbonization process. The subject of the invention is a Carbonization process. It is already known that cellulose can be obtained by highly concentrated Can cause saline solutions to swell or dissolve (see patent specification 275882, class 2g). But even this process is slow and only to such a minor extent in front of him that z. B. Herzog and Beck (Journal for Phys. Chemistry 192o, Volume 1z, Page 287) only one percent cotton wool by heating to 12o to 13o 'for 24 hours could gelatinize. Also the suggestion has already been made, by means of very dilute magnesium chloride solution to carbonize, taking after drying the material to be treated decomposes through prolonged heating (50 to 20 minutes) of magnesium chloride and thereby destroys the existing cellulose will. This procedure is quite cumbersome to perform and also requires a long time.
Nach dem den Gegenstand der Erfindung bildenden Verfahren gelingt es dagegen, auf ganz einfache Weise und in ganz kurzer Zeit, etwa 1 bis 2 Minuten, die Zellulose zu zerstören. Es wird dabei so vorgegangen, daß hochkonzentrierte Lösungen von Salzen der Alkalien oder Erdalkalien (z. B. eine 50prozentige Lösung von Chlorkalizium oder eine entsprechende Lösung von Chlormagnesium), denen eine geringe Menge von Säuren, z. B. 2 bis 3 Prozent Salzsäure, zugesetzt wurde, auf etwa x20 ° C erhitzt und das Gemisch von Wolle mit Baumwolle oder anderen Zellulosefasern oder irgendwelchen Seiden- oder Kunstseidenarten in die siedende Lösung eingetragen wird. Nach 1 bis 2 Minuten sind alle Fasern, mit Ausnahme der Wolle, angegriffen, so daß sie leicht entfernt werden können. Zweckmäßig wird unmittelbar nach der Reaktion ausgewaschen. Die Wolle wird durch das Verfahren nicht merklich geschädigt.The process forming the subject of the invention succeeds it, however, in a very simple way and in a very short time, about 1 to 2 minutes, destroy the cellulose. It is proceeded in such a way that highly concentrated Solutions of salts of alkalis or alkaline earths (e.g. a 50 percent solution of calcium chloride or a corresponding solution of magnesium chloride), which one small amount of acids, e.g. B. 2 to 3 percent hydrochloric acid, was added heated to about x20 ° C and the mixture of wool with cotton or other cellulose fibers or any kind of silk or rayon added to the boiling solution will. After 1 to 2 minutes, all fibers, with the exception of the wool, are attacked, so that they can be easily removed. It is useful immediately after the reaction washed out. The process does not noticeably damage the wool.
