Camphor (/ ˈ k æ m f ər /) is a waxy, colorless solid with a strong aroma. [5] It is classified as a terpenoid and a cyclic ketone.It is found in the wood of the camphor laurel (Cinnamomum camphora), a large evergreen tree found in East Asia; and in the kapur tree (Dryobalanops sp.), a tall timber tree from South East Asia.
Wood is an organic material and decays under biological and chemical degradation when buried or submerged above water or soil. Wood, an organic material produced by plants, are chemically composed of: carbohydrates (cellulose and hemicellulose), lignin and other components (aliphatic acids, alcohols, proteins and inorganic substances) in a ...
Industrially, a racemic mixture of camphor is used, leading to a racemic mixture of borneol and isoborneol. The chirality can be controlled by changing the chirality of camphor: (+)-camphor gives (−)-isoborneol and (+)-borneol. [7] Reduction of camphor with sodium borohydride (fast and irreversible) gives instead the diastereomer isoborneol.
The species contains volatile chemical compounds in all plant parts, and the wood and leaves are steam distilled for the essential oils. Camphor laurel has six different chemical variants called chemotypes, which are camphor, linalool, 1,8-cineole, nerolidol, safrole, and borneol. In China, field workers avoid mixing chemotypes when harvesting ...
Camphora parthenoxylon is known variously as Selasian wood, [4] saffrol laurel, [5] or Martaban camphor wood in English. [6] It has the outdated heterotypic synonym Laurus porrecta ( Roxb. The species name parthenoxylon derives from parthenos xylon ( Greek : παρθενός ξύλον ), meaning "virgin wood".
Unlike naphthalene and dichlorobenzene, camphor has medicinal applications and is not regarded as a carcinogen, though it is toxic in large doses. Red cedar wood and oil is also used as an alternative moth repellent. [18] Pheromone traps are also an effective diagnostic tool and can sometimes be an effective control tool to protect valuable ...
Wood science [1] is the scientific field which predominantly studies and investigates elements associated with the formation, the physical and chemical composition, and the macro- and microstructure of wood as a bio-based and lignocellulosic material.
Cyclohexanol is the organic compound with the formula HOCH(CH 2) 5.The molecule is related to cyclohexane by replacement of one hydrogen atom by a hydroxyl group. [4] This compound exists as a deliquescent colorless solid with a camphor-like odor, which, when very pure, melts near room temperature.
