Comment on solubility

Solubility of Butan-1-ol and Propane-1,2-diol

Both butan-1-ol (C4H10O) and propane-1,2-diol (C3H8O2), commonly known as propylene glycol, exhibit interesting solubility characteristics due to their molecular structure.

Butan-1-ol

Butan-1-ol is a polar alcohol, which enhances its ability to dissolve in water compared to non-polar compounds. Its solubility can be summarized as follows:

  • At room temperature, it is moderately soluble in water, with a solubility of approximately 7.8 g/100 mL.
  • Its solubility decreases in non-polar solvents, making it less compatible with hydrocarbons.
  • It can also dissolve in a variety of organic solvents such as ethanol and ether.

Propane-1,2-diol

Propylene glycol is another highly soluble compound due to the presence of two hydroxyl (–OH) groups:

  • It is completely miscible with water in all proportions, allowing for easy blending in aqueous solutions.
  • Additionally, it has good solubility in various organic solvents, including acetone and ethanol.
  • This makes propane-1,2-diol an excellent solvent and carrier for many chemical applications.

The degree of solubility in water and other solvents is primarily driven by the ability of these compounds to engage in hydrogen bonding, which facilitates their interaction with polar molecules like water.

In summary, both butan-1-ol and propane-1,2-diol demonstrate significant solubility in water and other solvents, but the specifics differ due to their unique structural properties.
