Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Sesquiterpenes: A Monograph The chemical study of the terpenes proper and of allied oxygen derivatives has opened up a fruitful field of research and made possible the rapid development of the volatile oil industry. Not only has this industry been placed on a scientific and permanent basis, but pure science as well has profited greatly, for some of the most important theories in organic and physical chemistry have sprung out of, or have found a most fruitful field in the study of this class of hydro carbons and their derivatives.

Its physical constants as found by various investigators is given in the following tabulation, the arrangement being chronological, giving at the same time the order of purity. All these samples were prepared from oil of cloves. Williams (1858): B. p. 251; dno=0.9016. Church (1875): B. p. 253.9 (corr.); d15=0.905.

Schreiner and Kremers also determined the indices of refraction for the three hydrogen lines, the dispersion between the lines being also given. 1.49694.01136, H,3 1.5083o.01834 I.00698 J Hr 1.51528) The molecular refraction agrees with two double bonds. Only caryophyllene obtained from clove oil has been considered in the above list, because even moderately pure samples of this hydrocarbon have not been prepared from the other oils, and also because of the contradictory statements found for the hydrocarbon of copaiba oil, which was discussed in the historical part and under copaiba oil in the section on occurrence. Chemical Properties and Derivatives. Caryophyllene yields with hydrochloric acid a crystalline dihydrochloride, which is quite stable. Upon hydration it gives a mono' hydrate, which appears to be a saturated compound. It also gives a nitrosochloride, a nitrosate and a nitrosite. These nitroso-comp. ounds and also the hydrate yield a number of other derivatives. It takes up four atoms of bromine but no crystalline...
