WebWhen ethyl-4-aminobenzoate reacts with hydrochloric acid, the amine hydrochloride salt of ethyl-4-aminobenzoate is formed. i.e. Because it is an ionic salt, ethyl-4-aminobenzoate hydrochloride is far more soluble than ethyl-4-aminobenzoate itself. What are the products of the reaction between ethyl ester and hydrochloric acid? WebFor Ethyl p- aminobenzoate, the only precipitate that was found in aqueous layer should only be 1M HCl. Because Ethyl p-aminobenzoate has an amine that acts as a base functional group, which will react with strong acid HCl. Therefore, it remained in HCl aqueous layer and precipitate out when heating up instead of ether layer.
