Baryta transforms this into acetate of baryta and tetrethylenic alcohol. 
This last is a thick colorless neutral liquid, soluble in water and boiling 
above 300°. 
Oxyd of ethylene is also capable of combining with diacetie glycol to 
form polyethelenic acetates.

This reaction is comparable with that whick transforms acetate of lead 
into basic acetate, when the neutral salt is brought into contact with an 
excess of oxyd of lead.

The basic properties of oxyd of ethylene are especially shown ne 8 
action which it exerts upon saline solutions. When the oxyd is mixed 
with a concentrated solution of chlorid of magnesium, the liquid after 
some hours solidifies; magnesia is precipitated, while chlorhydrate nf 
oxyd of ethylene is formed. |
