Ethyl propanoate is an ester compound and ethyl propyl ether is an ether compound. Therefore we have to brake (hydrolysis of ether) ester to different compounds to prepare ether.
Esters hydrolysis can be done by using an acid or alkali.
You can see in both molecules are different in their structures. As a organic compound, we can only use ethyl propanoate.
There are five carbon atoms in ethyl propyl ether.
Ethyl propanoate is an ester compound which can be prepared from reaction of an acyl chloride and an alcohol.
Steps of preparing ethyl propyl ether from ethyl propanaote are explained below. n this section you will learn about ester hydrolysis and ether preparing.
Ether is prepared by reaction of sodium salt of alcohols and alkyl halide. Sodium ion and halide ion eliminated to give NaX (X=Cl, Br, I) while ether is produced.
Ethyl propanoate hydrolysis is done by concentrated sulfuric acid, which is acidic hydrolysis. It gives ethanol (alcohol) and propanoic acid. But remember that, this reaction is reversible and does not occur 100% hydrolysis.
With aqueous NaOH, ethyl propanoate hydrolysis will give ethanol and sodium propanaote. To recover propanoic acid from sodium propanaote, add concentrated HCl solution.
Ethanol and propanoic acid can be separated by a physical separation method because their physical properties are different.
Separated ethanol reacts with sodium metal (Na) to give sodium ethoxide which is a strong base.
We cannot use aqueous NaOH to prepare sodium ethoxide.
Propanoic acid is reduced to propanol by LiAlH4.
Propanol reacts with PCl3 to chloropropane which is an alkyl halide compound.
Also wwe can use PCl5, SOCl2 to prepare chloropropane.
As chloropropane, bromopropane can be used in this conversion to prepare ethyl propyl ether.
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.
