Solution

Preparation of ether: There are many methods by which we can prepare ether. a very famous example to prepare ether is as follows:

Williamson synthesis reaction: In this reaction, haloalkane reacts with sodium alkoxide to form ether and sodium salt.

R-X+R-ONadryetherR-O-R+NaXhaloalkanesodiumethersodiumalkoxidesalt

For example,

CH3-Cl(aq)+CH3ONa(aq)dryetherCH3-O-CH3(aq)+NaCl(aq)

Uses of Dimethyl ether:

It is a colourless volatile poisonous liquid compound used as a solvent, fuel, aerosol, propellant, and refrigerant. Dimethyl ether (DME) is a synthetically produced alternative to diesel for use in specially designed compression ignition diesel engines.

  • It is the first member of the ether series.
  • It is used extensively in the chemical industry and as an aerosol propellant.
  • Dimethyl ether is a good solvent and has the unique property of high water solubility, compared to other propellants.
  • It has frequently been used with aqueous aerosols.

Hence, the chemical name of CH3OCH3 is dimethyl ether.
