   Nachdem alles Benzol   eingetragen ist, rührt   man noch eine Stunde lang. 



   Die   Benzol-Kampferlösung   wird dann von der   Chromlauge abgetrennt, mit Wasser und   Natronlauge bis zur vollständigen Entfärbung gewaschen, mit Kochsalz getrocknet und nach dem Filtrieren des Lösungsmittels abdestilliert. Es hinterbleiben 95 Teile Kampfer, der ohne weitere Reinigung bei 175 bis   1760 schmilzt.   



   Die in den Beispielen genannten Zusatzmengen en Benzol sind natürlich abhängig

   After all the benzene has been added, the mixture is stirred for another hour.



   The benzene-camphor solution is then separated from the chromium hydroxide solution, washed with water and sodium hydroxide solution until completely discolored, dried with sodium chloride and, after the solvent has been filtered off, distilled off. 95 parts of camphor remain, which melts at 175 to 1760 without further purification.



   The amounts of benzene added in the examples are of course dependent
