In 1821, John Kidd cited these two disclosures and then described many of this substance's properties and the means of its production. He proposed the name naphthaline , as it had been derived from a kind of naphtha (a broad term encompassing any volatile, flammable liquid hydrocarbon mixture, including coal tar). [ 16 ]
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.
A non-physical standard state is one whose properties are obtained by extrapolation from a physical state (for example, a solid superheated above the normal melting point, or an ideal gas at a condition where the real gas is non-ideal). Metastable liquids and solids are important because some substances can persist and be used in that state ...
Camphoric acid, C 10 H 16 O 4 [citation needed] or in Latin form Acidum camphoricum, is a white crystallisable substance obtained from the oxidation of camphor. It exists in three optically different forms; the dextrorotatory one is obtained by the oxidation of dextrorotatory camphor and is used in pharmaceuticals .
It is a white solid with a camphor-like odor. It is the simplest diamondoid. The discovery of adamantane in petroleum in 1933 launched a new field of chemistry dedicated to the synthesis and properties of polyhedral organic compounds. Adamantane derivatives have found practical application as drugs, polymeric materials, and thermally stable ...
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.
Borneol can be synthesized by reduction of camphor by the Meerwein–Ponndorf–Verley reduction (a reversible process). 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 ...
It is a minor constituent of many essential oils such as turpentine, cypress oil, camphor oil, citronella oil, neroli, ginger oil, valerian, and mango. [5] It is produced industrially by isomerization of the more common alpha-pinene using a solid acid catalyst such as titanium dioxide .
