Laboratory Preparation Of Diethylether(ethoxyethane)

Molecular Formula:-C4H10O Common Name:-Diethylether IUPAC Name:-Ethoxyethane Principle:- In the laboratory ethoxyethane is prepared by dehydrating ethanol with c.H2SO4 in the ratio of 2:1 at 140C temperature. The reaction completes in two steps: 1)Formation of ethylhydrogen sulphate at 100C CH3CH2OH + conc.H2SO4 —-> CH3CH2HSO4 + H2O 2)Formation of diethylether at 140C CH3CH2HSO4 + CH3CH2OH —-> CH3CH2-O-CH2CH3…
