ACTION OF CHLORINE ON Sinicic Eruyp. 
? 
Not even a trace of chlorid of ethyl is produced. In order to 
avoid the formation of products containing too large a propor- 
tion of chlorine, the operation is interrupted from time to time 
and all of the liquid, which boils at a temperature lower than 
160°, is distilled off, and the distillate is treated as before with 
chlorine. Finally the residues thus obtained are subjected to @ 
fractional distillation. ae 
Although we operated on a considerable quantity of silicic 
ethyd, and made a large number of fractional distillations of 
the chlorated product, we were unable to isolate bodies having 
constant boiling points and corresponding in composition to the 
mono- and bi-chlorated silicic ethyd. Analyses were made of 
the products which distilled at different temperatures after 4 
number of fractional distillations.

Repeated distillation decomposes partially the chlorated com- 
ound, and products having the same boiling-point contain 2
