Sulfanilic acid

Vedclass · Answer

(D) When aniline is treated with concentrated sulfuric acid,it forms aniline hydrogen sulfate. Heating aniline hydrogen sulfate at $453 - 473 \, K$ leads to a rearrangement reaction known as baking process. This results in the formation of $p$-aminobenzenesulfonic acid,which is commonly known as sulfanilic acid. The reaction is: $C_6H_5NH_2 + H_2SO_4$ $\rightarrow C_6H_5NH_3^+HSO_4^-$ $\xrightarrow{453-473 \, K} NH_2-C_6H_4-SO_3H + H_2O$.

What is obtained when aniline hydrogen sulfate is heated with sulfuric acid at $453 - 473 \, K$?
