54 REPORT OF SCHIMMEL § Co. OCTOBER 1914/APRIL 1915. 
brown colour and of an odour similar to, but weaker than, clove oil. The following 
constants were established: diso 1,0933; # — 3°11’; nps0o 1,54332; phenol percentage 
(ascertained with 3 p.c. caustic soda solution) 88 p.c.; soluble in 1,8 volume and 
more of 70 p.c. alcohol. Compared with clove oil, the specific gravity its remarkably 
high, for it exceeds even that of eugenol (diso 1,071 to 1,074). This was even more 
pronounced with the specific gravity of the separated phenols, which was 1,1210 (15°). 
The reason for this phenomenon is to be found in the fact that the phenols consist 
of only 60 p.c. of eugenol, the balance being made up of a solid combination. 
Calculated on the original oil its content of this latter body amounts to about 
35 p.c. and to about 53 p.c. of eugenol. 
The solid phenol has a weak, paraffin-like odour and is almost insoluble in water, 
but it dissolves more or less readily in organic solvents, as well as in alkali liquor. 
' From alcohol it crystallizes in fine, bold crystals‘of a m.p. 44 to 45,5°. At 754 mm. 
it boils between 309 and 310° and at 4 mm. from 146 to 149°. The rotation was 
found to be + 0°, the specific gravity in the melted state at 15° was 1,188. A strong 
reaction was obtained, with benzoyl chloride, the benzoyl combination, after repeated 
recrystallization from alcohol, melting at 87 to 88°. | 
Yama-nikkei bark Oil. An oil obtained by us from Yama-nikkei bark (wild cin- 
namon bark; N. O. Lauraceae) showed the following constants: diso 0,9245; ap) + 8° 34’; 
Np200 1,47779; acid v. 0,6; ester v. 14,8; soluble in 1 volume and more of 80 p.c. alcohol. 
The yield was from 1,77 to 2,1 p.c. 
The oil was of a light yellow colour and smelled strongly of camphor, with a 
somewhat ginger-like by-odour. The bulk distilled from 75 to 95° (6 mm.) and soli- - 
dified in the cold to a camphor paste, from which camphor was obtained, and purified 
by sublimation; m. p. 175°. With semicarbazide this camphor yielded a semicarbazone 
of the m. p. 236°; a 25 p.c. solution in chloroform showed a slight optical rotation, 
viz., —0°10’ in a 20 mm. tube. Judging from its odour the fraction obtained at the 
commencement of the distillation, from 40 to 75° (6 mm.), appears to contain terpenes 
and cymene; the bark originated from Japan.
