This product contained 27, of a per cent tof chlorine and we 
found, that the only way to free the methylic ethers el pipe 
from chlorine (probably contained in a chlorhydrine) is to heat 
them in a sealed tube at 180° with an excess of methylic alco- 
hol. After this treatment ‘ed produc was distilled again at
