What is the Difference Between Adipic Acid and Salicylic Acid?
🆚 Go to Comparative Table 🆚Adipic acid and salicylic acid are both organic compounds containing carboxylic acid groups. The key difference between the two lies in the number of carboxyl groups per molecule.
- Adipic Acid: Contains two carboxyl acid groups per molecule. It is a precursor for the production of nylon and is also used in the manufacturing of synthetic fibers and polymers.
- Salicylic Acid: Contains one carboxyl acid group per molecule. It is used as a medication to help remove the outer layer of the skin and is also known for its anti-inflammatory and anti-acne properties. It is often used as a food preservative.
In addition to the difference in the number of carboxyl groups, adipic acid and salicylic acid exhibit different solubility properties in water. Adipic acid has a solubility of 24 g/L at 298 K, while salicylic acid has a solubility of 2 g/L at 293 K, indicating that adipic acid is much more water-soluble than salicylic acid.
Comparative Table: Adipic Acid vs Salicylic Acid
Here is a table comparing the differences between adipic acid and salicylic acid:
Property | Adipic Acid | Salicylic Acid |
---|---|---|
Chemical Formula | (CH2)4(COOH)2 | C6H4(OH)COOH |
Number of Carboxyl Groups | 2 | 1 |
Occurrence | Mostly synthetic, can occur rarely in nature | Obtained from natural sources such as willow bark and wintergreen |
Odor | Odorless | Aromatic |
Production | Produced from a mixture of cyclohexanone and cyclohexanol | Produced from natural sources or synthetically |
Uses | Precursor for the production of nylon, lubricants, and plasticizers | Used in the production of aspirin, topical acne treatments, and as an antiseptic |
Adipic acid and salicylic acid are both organic compounds containing carboxylic acid groups as their functional groups. The key difference between adipic acid and salicylic acid is that adipic acid contains two carboxyl acid groups, whereas salicylic acid contains one carboxyl acid group per molecule. Additionally, adipic acid is primarily synthetic and is used in the production of nylon, lubricants, and plasticizers, while salicylic acid is obtained from natural sources such as willow bark and wintergreen and is used in the production of aspirin, topical acne treatments, and as an antiseptic.
