When salicylic acid is treated with acetic anhydride in the presence of concentrated H2SO4, it undergoes a process known as acetylation. This reaction is commonly used to synthesize aspirin, also known as acetylsalicylic acid. Here are the steps:

1. First, the hydroxyl group (-OH) on the salicylic acid molecule reacts with the acetic anhydride. This is facilitated by the acid catalyst, concentrated H2SO4.

2. The acetic anhydride donates an acetyl group (CH3CO) to the salicylic acid, replacing one hydrogen atom of the hydroxyl group.

3. This results in the formation of an ester linkage (COO) between the two molecules, creating acetylsalicylic acid and a byproduct of acetic acid.

4. The reaction can be represented by the following chemical equation:

C7H6O3 + (CH3CO)2O → C9H8O4 + CH3COOH

In this equation, C7H6O3 represents salicylic acid, (CH3CO)2O represents acetic anhydride, C9H8O4 represents acetylsalicylic acid (aspirin), and CH3COOH represents acetic acid.
