Adding concentrated sulfuric acid, a strong dehydrating agent, shifts the equilibrium to the products side by removing the water as it is formed. Equation 2 illustrates a specific example of an esterification reaction, that of methyl alcohol and acetic acid, to form methyl acetate.The systematic name for acetic acid is ethanoic acid, and the systematic name for the ester product is methyl ethanoate.dding concentrated sulfuric acid, a strong dehydrating agent, shifts the equilibrium to the products side by removing the water as it is formed.
