Webter·pene. One of a class of hydrocarbons with an empiric formula of C 10 H 16, occurring in essential oils and resins. Acyclic terpenes may be regarded as isomers and polymers of isoprene units; cyclic forms include menthane, bornane, and camphene. Terpenes containing 15, 20, 30, 40, etc., carbon atoms are called sesquiterpenes, diterpenes ...

Web30 Oct 2005 · Hydration and isomerization of the α-pinene to several alcohol or terpenic hydrocarbons have been studied since the 1940s, when Mosher [5] studied the isomerization of the α-pinene in acid media using 1-chloro-4-naftalen sulfonic acid. There is a lack of solid catalysts able to carry out the reaction of hydration of the α-pinene to terpineol ... Terpenes are colorless, although impure samples are often yellow. Boiling points scale with molecular size: terpenes, sesquiterpenes, and diterpenes respectively at 110, 160, and 220 °C. Being highly non-polar, they are insoluble in water. Being hydrocarbons, they are highly flammable and have low specific … See more Terpenes are a class of natural products consisting of compounds with the formula (C5H8)n for n > 1.
