26 Sep 1977TL;DR: In this article, cyclic terpene compounds are converted into their corresponding open-chain isomers by thermal isomerization at a temperature of at least 300°C in the presence of a solid material comprising a metal or metal oxide selected from the class consisting of alkali metals, alkaline earth metals, transition metals and mixtures thereof supported on a carrier having a specific surface area in the range of about 0.01 to about 20 m 2 /g.
Abstract: Cyclic terpene compounds selected from the class consisting of pinane, alpha-pinene, beta-pinene and mixtures thereof are converted into their corresponding open-chain isomers-e.g., dihydromyrcene, allo-ocimene and myrcene-by thermal isomerization at a temperature of at least 300° C in the presence of a solid material comprising a metal or metal oxide selected from the class consisting of alkali metals, alkaline earth metals, transition metals and mixtures thereof supported on a carrier having a specific surface area in the range of about 0.01 to about 20 m 2 /g.

TL;DR: In this paper, the alpha-pinene thermal isomerization reaction is combined with operations of rectifying and separating the alphapinene, so that the transformation process from ocimene to alloocimene is effectively inhibited.
Abstract: The invention discloses a method for preparing ocimene from thermo isomeric alpha-pinene in a liquid phase, and belongs to a method for preparing ocimene According to the method, no organic solvent or catalyst is needed; nitrogen carrier gas is not needed; only a pure alpha-pinene liquid needs to flow through the surface of an electrical heating nickel chrome wire at a proper speed, and is subjected to thermal isomerization reaction; and a reaction temperature of 300-800 DEG C is estimated while the temperature of the alpha-pinene in a liquid environment in a decompressed state is kept at 50-100 DEG C, so that the product after thermal cracking is rapidly cooled to below 100 DEG C by the surrounding liquid; and the transformation process from ocimene to alloocimene is effectively inhibited The alpha-pinene thermal isomerization reaction is combined with operations of rectifying and separating the alpha-pinene, so that the transformation rate of raw materials and the yield of the ocimene are improved; a good effect is reached; the method is simple to operate; the equipment cost is low; and the ocimene is high in selectivity, high in yield, good in quality, free of pollution and large in economic benefits
