Prolonged heating of camphor and iodine or carvone with glacial phosphoric acid have also been demonstrated. The dehydrogenation of carvone with a palladium-carbon catalyst has been established. [5] It has also been prepared by transalkylation of isopropylated cresols. [19] It is extracted from Origanum oil by means of a 50% potash solution.
