Not illustrated. 1902 edition. Excerpt: ...this alcohol as identical with oxy-2-hexahydro-p-cymene (tetrahydrocarveol), which was prepared by Baeyer in the reduction of dihydrocarveol, and by Wallach by the reduction of carvenone. The results of Wallach's1 researches fully establish Semmler's view. Carvotanacetone unites with hydrogen sulphide in ammoniacal solution;2 the product melts at about 95. Carvotanacetoxime, C10H18NOH, is obtained from crude carvotanacetone, as already indicated; it crystallizes from methyl alcohol, and melts at 92 to 93. It is optically inactive (Wallach Wallach obtained an oxime having the same melting point (93 to 94) from the fraction of thuja oil, which boils at 220 to 230. Carvotanacetone semicarbazone forms orthorhombic tablets or acute prisms, and melts at 177 (Baeyer3). According to Harries, the oxaminoxime of carvotanacetone sinters at 155 and melts at 162; it was not obtained quite pure, hence Harries 4 regards it as probable that carvotanacetone is a mixture of the racemic form of dihydrocarvone with other compounds. When carvotanacetone is oxidized with a dilute solution of potassium permanganate, it yields pyruvic and isopropylsuccinic acids. From this fact Semmler2 concludes that carvotanacetone is an orAo-terpene ketone, and that the pseudo-ketone corresponding to it is found in terpenonef C10H16O (obtained from tetrahydrocarvone). 11.

Excerpt from The Chemistry of the Terpenes I may refer to the chapter of introduction for the principal points of view from which the compilation of the monograph has proceeded; I still regard these principles as correct.
