Chemistry 22- Camphor
 Camphor is a waxy, white or transparent solid with a strong, aromatic odor.[3] It is a terpenoid with the chemical formula C10H16O. It is found in wood of the camphor laurel (Cinnamomum camphora), a large evergreen tree found in Asia (particularly in Borneo and Taiwan) and also of Dryobalanops aromatica, a giant of the Bornean forests. It also occurs in some other related trees in the laurel family, notably Ocotea usambarensis. It can also be synthetically produced from oil of turpentine. It is used for its scent, as an ingredient in cooking (mainly in India), as an embalming fluid, in religious ceremonies and for medicinal purposes. A major source of camphor in Asia is camphor basil. Nor camphor is a camphor derivative with the three methyl groups replaced by hydrogen. Modern uses include as a plasticizer for cellulose nitrate, as a moth repellent, in embalming, and in fireworks. A form of anti-itch gel currently on the market uses camphor as its active ingredient. Historically it has been used in medicine. Camphor is readily absorbed through the skin and produces a feeling of cooling similar to that of menthol and acts as slight local anesthetic; however, it is poisonous when ingested and can cause seizures, mental confusion, irritability, and neuromuscular hyperactivity. taken from: http://en.wikipedia.org/wiki/Camphor taken from: http://www.3dchem.com/molecules.asp?ID=203# |
