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
