Decanoic Acid: A Comprehensive Overview

1. Introduction

Decanoic acid, also known as capric acid, is a saturated fatty acid with the chemical formula C10H20O2. It is classified as a medium-chain fatty acid due to its ten-carbon chain length. Decanoic acid is naturally found in various animal and plant fats, including coconut oil and palm kernel oil. It plays significant roles in nutrition, pharmaceuticals, and industrial applications.

2. Chemical Properties

• Chemical Formula: C10H20O2
• Molecular Weight: 172.26 g/mol
• Structure: Decanoic acid features a straight ten-carbon chain with a carboxylic acid functional group (-COOH) at one end.
• Physical State: At room temperature, decanoic acid is a white crystalline solid with a characteristic fatty odor.

3. Physical Properties

• Melting Point: Decanoic acid melts at around 31.6°C (88.9°F), making it a solid at room temperature in most climates.
• Boiling Point: It boils at approximately 269°C (516°F).
• Solubility: Decanoic acid is sparingly soluble in water but dissolves readily in organic solvents such as ethanol, ether, and chloroform.
• Odor: It possesses a characteristic fatty odor, which can be perceived even at low concentrations.

4. Industrial Applications
