Ethyl propanoate is an ester compound and ethyl propyl ether is an ether compound. Therefore we have to brake (hydrolyze of ether) ester to different compounds to prepare ether.
Steps of preparing ethyl propyl ether are explained below.
Ether is prepared by reaction of sodium salt of alcohols and alkyl halide.
Ethyl propanoate hydrolyzes by concentrated sulfuric acid, which is acidic hydrolysis. It gives ethanol (alcohol) and propanoic acid. (carboxylic acid compound).
Ethanol and propanoic acid can be separated by a physical separation method because their physical properties are different.
Separated ethanol reacts with sodium to give sodium ethoxide which is a strong base.
Propanoic acid is reduced to propanol by LiAlH4.
Propanol reacts with PCl3 to chloropropane which is an alkyl halide.
Ethyl propyl ether is given as the product by the reaction of chloropropane and sodium ethoxide. NaCl is eliminated to give the product. No other reagent is required to occur this reaction.
