Boleng:

- E na le ponahalo e tšoeu ea kristale 'me e na le monko o matla oa camphor.

- E qhibiliha ka har'a metsoako ea tlhaho e kang ethanol, ether le chloroform, e qhibilihang hanyane ka metsing.

- E na le monko o hlabang le tatso ea linoko, 'me e na le phello e khopisang mahlong le letlalong.

 

Mokhoa:

- Camphor e ntšoa haholo-holo lekhapetleng, makaleng le mahlakung a sefate sa camphor (Cinnamomum camphora) ka distillation.

- Tahi e ntšitsoeng ea sefate e kena mehatong ea phekolo e kang dehydration, nitration, lysis, le cooling crystallization ho fumana camphor.
