Oxide of ethylene also¥ unites with glycol under the same 
circumstances as with water. The principal product of the reac- 
tion is the above intermediate ether, €4H!° 0%; but when this 
has distilled over, a very thick colourless liquid is obtained which 
boils at about 290°. It is formed by the combination of two 
atoms of oxide of ethylene with one atom of glycol, and its com- 
position is expressed by the formula 
2(6?H*0) + G? HSO?=C8 HH" 04, 
Oxide of ethylene. Glycol. New body. 
It is also formed, but in very small quantities, by the action of 
oxide of ethylene on water :

Oxide of ethylene. New body. 
Hence one, two, or three atoms of oxide of ethylene can unite 
with one atom of water to form, by direct synthesis, more and 
more complicated bodies, which are nevertheless very simple in 
their molecular constitution. Wurtz considers these bodies to be 
alcohols. If the name ethylenic alcohol be given to glycol, the 
other two bodies may be named diethylenic alcohol and triethy- 
lenic alcohol. The following formule indicate the relations of 
these bodies to each other :—
