Comment on solubility

Solubility of Butan-1-ol (C4H10O)

Butan-1-ol, commonly known as n-butanol, exhibits interesting solubility characteristics that can influence its applications in various fields. Here are some key points regarding its solubility:

  • Butan-1-ol is soluble in water due to its ability to form hydrogen bonds with water molecules, attributable to its hydroxyl (-OH) functional group.
  • The solubility limit is approximately 7.9 g per 100 mL at room temperature, indicating that while it dissolves well, it does not exhibit complete miscibility. However, as the temperature increases, solubility can also be expected to increase.
  • In addition to its water solubility, butan-1-ol is compatible with organic solvents such as ether and alcohols, making it a versatile compound in chemical reactions and formulations.
  • Its log P value (partition coefficient) suggests moderate lipophilicity, implying that it can partition into lipid (fat) layers, which influences its behavior in biological systems.

Understanding the solubility of butan-1-ol is crucial, particularly in industrial and laboratory settings, where its role as a solvent or reagent may require specific solubility conditions. As noted, the property of solubility directly correlates with its utility in applications ranging from pharmaceuticals to fuel additives.
