Terpenes are local irritants and can cause gastrointestinal disturbances if ingested. Terpenoids (mono-, sesqui-, di-, etc.) have similar physical properties but tend to be more polar and hence slightly more soluble in water and somewhat less volatile than their terpene analogues. See more Terpenes are a class of natural products consisting of compounds with the formula (C5H8)n for n > 1. Comprising more than 30,000 compounds, these unsaturated hydrocarbons are produced predominantly by See more Terpenes are major biosynthetic building blocks. Steroids, for example, are derivatives of the triterpene squalene. Terpenes and … See more Terpenes are colorless, although impure samples are often yellow. Boiling points scale with molecular size: terpenes, sesquiterpenes, and diterpenes respectively at 110, … See more Terpenes can be visualized as the result of linking isoprene (C5H8) units "head to tail" to form chains and rings. A few terpenes are linked “tail to tail”, and larger branched terpenes may be linked “tail to mid”. Formula Strictly speaking all … See more The term terpene was coined in 1866 by the German chemist August Kekulé to denote all hydrocarbons having the empirical formula C10H16, of which camphene was one. Previously, many hydrocarbons having the empirical formula C10H16 … See more The one terpene that has major applications is natural rubber (i.e. polyisoprene). The possibility that other terpenes could be used as precursors to produce synthetic polymers has been investigated as an alternative to the use of petroleum-based … See more Isoprene as the building block Conceptually derived from isoprenes, the structures and formulas of terpenes follow the biogenetic … See more Weband phenol-modified polyterpene. The terpene phenolic resins have a relative high softening point of about 100 - 160°C due to their higher polarity whereas the softening point of (unmodified) polyterpenes greatly depends on the It typically varies from about 10 to 135°C.
