Description
Verfahren zur Wiedergewinnung von Kampfer aus Gasgemischen. Für diese Anmeldung ist gernä@ dem L'nionsvertrage vom a. Juni igi i die Priorität auf Grund der Anmeldung in Frankreich vom ig. März mo beansprucht. Bei der Fabrikation von Celltiloid und :ihnlichen plastischen Massen entweichen Dampfe, welche, abgesehen von denn verwendeten Lös ttitgstiiittel, auch eine ziemlich heträchtliche Menge von Kampfer finit sich führen. je nach der Art der Fabrikation kann auf diese Weise his zu 7 Prozent des in Arbeit genoininenen Kampfers sich verflüchtigen.Process for the recovery of camphor from gas mixtures. For this Registration is welcome to the L'nion contract of a. June igi i the priority due the registration in France from ig. Claimed March mo. In the manufacture of Celltiloid and similar plastic masses escape from vapors, which apart from that of the solvents used, also a considerable amount run from camphor finitely. depending on the type of fabrication can be done in this way up to 7 percent of the internal camphor in work will evaporate.
Bisher war e:: nur üblich, den Kampfer in den bekannten Standardwäschern teilweise zur Alpscheidung zu bringen und das Gas nachträglich von seinem Gehalt an flüchtigen Lösungsmitteln durch Waschen finit verschiedenen Olen zu befreien. L`herdies wurden dort Verfahren verwendet, welche die N iederschlagttng des Kampfers und die teilweise Absorption der Liisungsmitteldämpfe durch Waschen der Gase mit Wasser bezwecken.Until now it was only common to use camphor in the well-known standard washers partly to bring to the alpine separation and the gas afterwards from its content to free them from volatile solvents by washing finitely different oils. L`herdies procedures were used there, which the knocking down of the camphor and the partial absorption of the solvent vapors by scrubbing the gases with them Purpose of water.
Die moderne Industrie ist bestrebt, unvollkoininene I-ückgewinnungsverfahren, wie z. B. die Berieselung mit Wasser, durch solche Absorptionsverfahren zu ersetzen, die eine vollständige Zurückhaltung der Uöstuigsinittel-,l:impfe gewährleisten.Modern industry strives to use incomplete recovery processes, such as B. to replace sprinkling with water with such absorption processes, which ensure complete restraint of the Uöstuigsinmittel-, oil vaccine.
Zu dieseln Verfahren zählt die Absorption niit aktiver Kohle und als bestes Verfahren die Waschung finit Plienolliomologen.Diesel processes include absorption with active carbon and as best practice washing finite plienolliomologists.
Bei Verwendung dieses Verfahrens hat inan bisher immer eine Abscheidung des Isainpfers vor (leg Absorption in Phenol in der bisher üblichen Weise durchgeführt, und zwar entweder durch Kühlung oder durch Waschen im Stanrlardwäsclier usw.When using this method, there has always been a deposition inan up to now the isainacrifice before (absorption in phenol carried out in the usual way, either by refrigeration or by washing in a standard washing machine, etc.
Weitere Versuche -haben gezeigt, daß die Phenole selbst vorzügliche Mittel darstellen, uni Katnpfer vollständig zu absorbieren. Die Stoffe werden von Phenolen in ganz ähnlicher Weise gebunden, wie dies z. B. für Äther, Alkohol oder Aceton nachgewiesen ist.Further experiments have shown that the phenols themselves are excellent Represent a means of fully absorbing the catnpfer. The fabrics are made by Phenols bound in a very similar way, as z. B. for ether, alcohol or Acetone is detected.
Dadurch kann nunmehr der Prozeß der Wiedergewinnung von Alkohol, Äther und anderen Stoffen aus Abgasen der Celluloidfabrikation finit der Gewinnung von Kampfer vereinigt und dadurch sehr bedeutend vereinfacht werden.This enables the process of recovery of alcohol and ether and other substances from exhaust gases from celluloid production finite the production of Camphor can be combined and thereby very significantly simplified.
Gemäß der Erfindung werden daher die Dämpfe von Kampfer gleichzeitig finit den sonstigen zur Absorption gelangenden flüchtigen Lösungsmitteln vollständig aufgenornitien. Die Trennung voni Absorptionsinittel erfolgt hinsichtlich der Lösungsmittel durch Erhitzen des Gemisches, hinsichtlich Kampfer durch Zerlegung des Genfisches finit Hilfe von Soda oder Alkali, wodurch Kampfer als wasserunlöslich zuriickbleibt, Die Plienolate können ihrerseits wieder durch Kohlensäure oder andere Säuren zerlegt und daraus die Phenole regeneriert werden.According to the invention, therefore, the vapors of camphor become simultaneous finite with the other volatile solvents that are absorbed recording arrangements. The separation of absorbents is in terms of solvents by heating the mixture; for camphor, by breaking up the Geneva table finitely with the help of soda or alkali, whereby camphor remains insoluble in water, The plienolates can be broken down again by carbon dioxide or other acids and from this the phenols are regenerated.
