Solution:

Ethyl benzoate is prepared by reacting benzoic acid and ethanol in the presence of dry $H C I$ . This reactioh is known as esterification reaction
$Benzoicacid C_{6} H_{5} COO H + Ethanol C_{2} H_{5} O H Dry H Cl Ethylbenzoate C_{6} H_{5} COO C_{2} H_{5}^{'} + H_{2} O$
This reaction proceed with equilibrium.
Therefore, $H_{2} O$ continuously removed from reaction. For preparation of ester product.
