The structural formula of isopropyl acetate and ethyl salicylate

isopropyl acetate, also known as isopropyl acetate, is the ester formed by acetic acid and isopropyl alcohol. Its structural formula is as follows:
\ [CH_3 - C (= O) - O - CH (CH_3) _2\]

From the above structural formula, it can be seen that the molecule is composed of acetyl (\ (CH_3 - C (= O) \)) and isopropoxy (\ (-O - CH (CH_3) _2\)).

Ethyl salicylate is the product of the esterification reaction between salicylic acid and ethanol. Its structural formula is:
\ [C_6H_4 (OH) - COO - C_2H_5\]

In this structure, one hydrogen atom on the benzene ring is replaced by a hydroxyl group (\ (-OH\)), and the other hydrogen atom is replaced by a carboxyl ethyl ester group (\ (-COO - C_2H_5\)).

In summary, isopropyl acetate and ethyl salicylate have different physical and chemical properties due to structural differences, and play their own unique roles in organic synthesis, fragrance and other fields.
