Understanding Chemistry for Advanced Level
Ethoxyethane is a solvent often used for extraction because: • Most organic
compounds dissolve well in it, while inorganic compounds tend to dissolve better
in water. • Ethoxyethane does not mix with water. So, to separate the organic
product ...
Ted Lister, Janet Renshaw, 1999
A Ethoxyethane (ether) was at one time used as an anaesthetic. Condensation
then occurs with a further molecule of phenol and the process continues until all
the aromatic rings are substituted in the 2, 4 and 6 positions. A molecular network
...

Separation, Purification and Identification
Ethoxyethane (diethyl ether) is chosen as the organic solvent in this case. A
150ml volume of ethoxyethane is added and, after shaking, the two liquids are
allowed to separate. Ethoxyethane is almost insoluble in water, and a distinct
boundary ...
