A NOTE ON THE PHENOLS OCCURRING IN SOME 
EUCALYPTUS OILS. |

[Received January 19, 1915.] 
So far as our knowledge goes phenolic bodies are absent in 
the greater portion of the essential oils of the various 
species of Hucalyptus, or, if occurring at all, are only 
present in very minute quantities, particularly in those 
usually found in commerce. In the oils of some species, 
however, phenols do occur, and it is the object of this note 
to record this fact. The chemistry of these bodies must 
be left for a subsequent paper. 
In the oil of EK. linearis of Tasmania a liquid phenol 
occurs in sufficient amount to enable its general characters 
to be determined, and as it does not appear to have been 
previously described we propose the name Tasmanol for it, 
as it appears to be most abundant in the oils of certain 
Tasmanian species, which, so far, are considered to be 
endemic in that island. Another species in which it occurs 
in fair amount is EK. Risdoni. 
The phenol was removed from the crude oil in the usual 
manner by shaking with aqueous sodium hydrate, washing 
the aqueous solution with ether to remove adhering oil, 
acidifying and extracting with ether. The residue, which 
contained a small amount of acetic and butyric acids, was 
washed with dilute sodium carbonate, extracted with ether, 
the ether removed and the phenol distilled. It boiled at 
268 — 273° O. (uncor.) and at 175° under 25 mm. pressure. 
It was optically inactive, the specific gravity at 23° was 
1°077, and the refractive index at 22° was1°5269. Besides
