It appears that, in a mixture of equal equivalents, the two chlo- 
rated products have a tendency to distil together at a constant 
temperature. Bauer* has noticed an analogous fact in regard 
to the bromids of ethylene and propylene. 
Distillation having been found ineffectual to separate the chlo- 
rated silicic ethyds, we sought to obtain a separation of these 
products, or better still, of their derivatives, by chemical means, 
and in this, after a number of experiments, we succeede 
We noted that the chlorated products are not attacked by an 
alcoholic solution of acetate of potassium, except at a high tem- 
perature, and also that the one containing two atoms of chlo- 
rine is more easily attacked than the other. In fact, the pro- 
duct containing most chlorine is destroyed at a temperature o 
130° to 140°, while the monochlorated product is not acted up-
