Aspirin is produced by the reaction of salicylic acid"(C_7H_6O_3)" with acetic anhydride "(C_4H_6O_3)" in the presence of "(H_3PO_4)" as catalyst .It gave Aspirin and acetic acid as products.


Reaction:


"C_7H_6O_3+C_4H_6O_3 \\Rightarrow C_9H_8O_4+C_2H_4O_2"


Ester is prepared by the reaction of acid with the alcohol and it also gave ester and water as products


Reaction:


"ROOH+R^1OH\\Rightarrow ROOR^1+H_2O"
