the Compound Athers of Benzolic Alcohol. 271 
est degree. But evidence of the correctness of Wicke’s view has 
been obtained in the various combinations formed by benzolic 
aleohol. 
The double zthers were obtained by Williamson’s method by 
double decomposition of chlorobenzole and the sodium combina- 
tions of the alcohols. Methylbenzolic ether, ce Hae FO% is 
obtained by adding an equivalent of chlorobenzole to 2 equiva- 
lents of sodium dissolved in pure and dry wood-spirit, and boil- 
ing for some time. The excess of wood-spirit is then distilled 
off, the residue mixed with water, and the liquid which rises to 
the surface removed by means of a pipette, dried and distilled. 
Methylbenzolic ether is a transparent liquid, insoluble in water, 
and heavier than that liquid; soluble in ether, alcohol and 
wood-spirit, and boils at 208° C., but not without partial decom- 
position. It has an odour resembling geranium. 
£Kthylbenzolic ether, na i O+, was prepared in the same 
way as methylbenzolic xther, to which it is very similar in 
properties. This is also the case with amylbenzolic ether,

The compound zthers of benzolic aleohol are obtained by the 
double decomposition of chlorobenzole and the silver salts of 
the corresponding acids. The acetic benzolic xther has alone 
been obtamed in a pure form; it crystallizes, while the others 
are thick viscous liquids, and cannot be distilled without de- 
composition.

Acetic benzolic eather, ce “ 022 $O%.— Two equivalents 
of dry acetate of silver are triturated with chlorobenzole, then 
placed in a flask and gently warmed. A violent action ensues, 
which results in decomposition if too large quantities are used. 
The mass is repeatedly extracted with ether, the filtered setherial 
extracts distilled off in the water-bath: the residual oil, freed 
from acetic acid by washing with soda and then with water, is 
then dissolved in ether and left to crystallize. Acetic benzolic 
zther occurs in white lustrous crystals, very similar to the swal- 
low-tail gypsum crystals. It melts at 36°, and solidifies to a 
crystalline mass, and cannot be distilled without decomposition. 
Treated with potash, it decomposes into hydruret of benzoyle and 
acetic acid. 
Valerianic and benzoic benzolic xthers were also prepared, but 
they could not be obtained pure; still less could the compound 
benzolic «ethers of the bibasic acids, sulphuric, oxalic, and suc- 
cinic acids.
