Isobutanol (IBA), also known as 2-Methyl-1-Propanol, is a colorless, transparent liquid with a distinctive odor. It has extensive industrial applications, including as a solvent, chemical intermediate, and fuel additive.
Understanding the water solubility of isobutanol (Isobutyl Alcohol, IBA) is essential for industrial buyers involved in coatings, fuels, pesticides, inks, resins, and chemical synthesis.
How Soluble Is Isobutanol in Water?
Isobutanol is slightly soluble in water.
Typical solubility at 20–25 °C:
≈ 80–90 g/L (around 8–9 wt%)
Above this level, phase separation occurs
Why Solubility Matters in Industrial Formulations?
Coatings, Inks & Adhesives
Lower water solubility helps:
- Reduce moisture absorption
- Improve resin compatibility
- Enhance film formation and leveling
- Preferred over ethanol or methanol in high-performance coatings
Pesticides & Agrochemicals
- Acts as a cosolvent that:
- Improves active ingredient dispersion
- Maintains formulation stability
- Helps prevent crystallization during storage
Fuels & Additives
- Lower affinity for water than ethanol
- Reduces risk of phase separation in gasoline blends
What are the properties of Isobutanol (IBA) ?
- Isobutanol is a flammable liquid whose vapors can form explosive mixtures with air.
- It exhibits good solubility, being miscible with ethanol and diethyl ether, and soluble in approximately 20 parts water.
- Isobutanol has a boiling point of about 108°C, a melting point of approximately -108°C, and a density of about 0.802 g/cm³.
