Ether, also called diethyl ether, is a volatile flammable liquid obtained by distilling a mixture of alcohol with an acid. It is used as a solvent, as an intermediate in chemical synthesis, and as a general anesthetic.
The arrangement of equipment in figure 1 is convenient where small quantities of ether are desired, while figure 2 shows an apparatus for manufacturing ether on a larger scale.
