Description

Colorless or white (translucent) crystals, granules or easily broken masses; penetrating aromatic odor, sublimes slowly at room temperature, slightly soluble in water, soluble in alcohol, ether, chloroform, carbon disulofide, solvent naphta and fixed volatile oils.

Derivation is steam distillation of the camphor-tree wood and crystallization. This product is called natural camphor, most of which is optically inactive, may be made from pinene, which is converted into camphene which by treatment with Acetic Acid and nitrobenzene becomes camphor, turpentine oil is also used.

A liquid form (camphor oil) is produced almost exclusively in Taiwan; formerly used in the manufacture of Sassafras Oil; the available supply is used chiefly as a fragrance or flavouring material and to some extent as a pharmaceutical product.
