A New Camphor Synthesis - Journal of the American …

Synthetic camphor is produced by converting α-pinene from turpentine to camphene to isobornyl acetate to isoborneol to camphor. Synthetic camphor is chemically identical to natural camphor but is optically inactive (racemic) (, 126–28; Kirk and Othmer 1982, 709–62).

X. Jones Reaction: The Oxidation of Borneol to Camphor

Several types of camphor substitutes have similar characteristics but different chemical structures. They include Borneo camphor (borneol) and bornyl chloride. Neither of these compounds was widely used but may have been mixed with camphor (, 126–28). Other camphor substitutes developed by industry include Lindol (Celanese Corp.), which is tricresyl phosphate ortritolyl phosphate; triphenyl phosphate; dehydranone (Union Carbide); and cyclohexyl levulinate. None of these products offered better characteristics than camphor (for less cost). None was used to replace camphor entirely, although small amounts were often added to the celluloid mixture. Worden lists the characteristics that make camphor the best “latent solvent” for cellulose nitrate:

Fanning 1 Synthesis of Camphor by the Oxidation of Borneol

The nitration of cellulose nitrate appears, on paper, to be a fairly simple reaction. However, no clear comprehensive mechanism has been found to describe it. Analysis of carefully controlled and nitrated cellulose indicates that the reaction is not as simple as was believed. The percentage of nitrogen in the resultant cellulose nitrate indicates that the reaction is not stoichiometric. The irregular nitration was thought to be a result of inhomogeneities in the original cellulose fibers .

Reduction of Camphor, Synthesis of Isoborneol

Camphor, (the pungent ingredient in chili peppers), and are plant-derived natural products well known for their sensory effects. Capsaicin and menthol are known to excite and subsequently desensitize sensory neurons by acting on two members of transient receptor potential (TRP) channel superfamily, vanilloid subtype 1 () and channel M8 (TRPM8), respectively. Thermo-sensitive transient receptor potential (Thermo-TRPs) cation channels are a subgroup of the transient receptor potential () superfamily of ion channels. They are understood to play a critical role in transduction of thermal and nociceptive information to the central nervous system. These thermoTRPs detect a wide range of temperatures spanning from noxious cold and heat as well as cool and warmth. Interestingly, all thermoTRP channels are apparently also chemosensitive, potentially enabling these channels to detect multiple sensory modalities.

Cellulose has an optically biaxial and positive unit cell and is highly birefringent. When nitrated the fibers become less birefringent and the optical activity changes from biaxial positive to uniaxial to biaxial negative with increasing nitrogen content. The refractive index of cellulose nitrate is lower than that of cellulose and drops even lower with increasing nitrogen content. The range is from 1.49 to 1.51 (, 210–11). Isolation of cellulose nitrate from celluloid for optical identification is problematic in that when cellulose nitrate is gelled by camphor it loses its original structure and, hence, many of its original optical characteristics.

, (pronounced /ˈkæmfə/) is a waxy, white or transparent solid with a strong, aromatic odor. It is a terpenoid with the chemical formula It is found in wood of the camphor laurel (), a large evergreen tree found in Asia (particularly in Sumatra, 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. Dried rosemary leaves (Rosmarinus officinalis), in the mint family, contain up to 20% camphor. 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, for medicinal purposes, and in religious ceremonies. A major source of camphor in Asia is camphor basil.
Norcamphor is a camphor derivative with the three methyl groups replaced by hydrogen.
