camphor, is penetrating. Specific gravity about 0,87 to o,gi. When 
cooled to — 20°, no separation takes place; when heated it is volatile, 
and boils from about 150° to 195°; it consists of pinene, phellandrene, 
cineol and dipentene. As it somewhat resembles turpentine oil, it is 
frequently used in practice instead of the latter. As this oil still 
contains a small quantity of camphor, it is possible to obtain a small 
amount of the latter by most careful distillation. The quantity of 
oil taken for the fractional distillation was in every case 1500 grams.

After these eight fractional distillations of white camphor oil, it still 
contains from 3,75 to 8 per cent camphor which, from an economical 
point of view, would appear to demand extracting by means of improved 
apparatus. 
Red Camphor oil. 
Red camphor oil is obtained from the crude camphor oil by means 
of fractional distillation, after white camphor oil and then camphor 
have been removed The portions boiling higher than camphor and 
white oil are collected; they represent a transparent, brown to dark- 
brown, mobile oil, which is volatile, and has a faint penetrating odour 
like camphor. Specific gravity about i to 1,035. It boils at 225° 
to 270°, and consists principally of safrol; it also contains eugenol, 
and further a very small quantity of camphor.
