Upon treating the enolacetate of the aldehyde with permanganate, there results teresantalic acid (m. p. 154 to 156). By shaking the normal sandal wood oil with bisulphite solution the aldehyde can also be obtained and in small amounts it may be identified by its semicarbazone. 8. Santalone, CnH16O. The second ketone occurring in the lower boiling portions of sandalwood oil is santalone. According to F. Miiller4), it boils at 214 to 215, 88 to 89" under 15 mm. pressure (?); d15 0,9906; I.--62. Schimmel 8 j Co.) found the following constants: b. p. 213 to 216; d15 0,9909; D--41 32'; nD20 1,50021. ') Report of Schimmel $ Co.

Santalone semicarbazone melts at 174 to 176, santalone oxime at 74,5 to 75,5. From the latter santalone cannot be regenerated by treatment with dilute sulphuric acid. 9. ketone, CuH16O. The santalone fraction contains a second, presumably isomeric ketone, the difficultly soluble semicarbazone of which melts at 208 to 209, the oxime at 97 to 99. 10. Santalene, C15H24. The occurrence of sesquiterpenes in sandal wood oil was first pointed out by H. von Soden and F. Miiller1). M. Guerbet2) then showed that two sesquiterpenes were present which he designated as -and-santalene. Properties and derivatives of both are recorded in vol. I, p. 336. There should be added, however, the physical constants of both which have since been determined more accurately by Schimmel $ Co.3). -Santalene: b.p....
