Product Overview

Isobutanol, also known as Isobutyl Alcohol or 2-Methyl-1-propanol, is a colorless, flammable liquid with a characteristic alcohol odor. Its CAS number is 78-83-1, with the molecular formula C₄H₁₀O and a molecular weight of approximately 74.12 g/mol. As an important industrial solvent and chemical intermediate, isobutanol is widely used in coatings, paints, adhesives, inks, chemical synthesis, plasticizers, and other industrial applications.

Physicochemical Properties

Isobutanol has good solvency and moderate volatility, making it suitable for applications requiring effective dissolution and controlled evaporation. It has a boiling point of approximately 108°C and a density of about 0.80 g/cm³ at 20°C. Isobutanol has limited solubility in water and good compatibility with many organic solvents, which contributes to its versatility as an industrial solvent.

Main Applications

Isobutanol is widely used as a solvent and chemical intermediate in various industries. Its major applications include:

  • Paints and coatings
  • Printing inks
  • Adhesives
  • Industrial solvents
  • Resin production
  • Plasticizer production
  • Chemical synthesis
  • Fine chemical manufacturing

It is also used as a raw material for producing isobutyl esters and other chemical derivatives, supporting applications across coatings, plastics, and specialty chemical industries.

Industrial Application Value

With its good solvency, suitable volatility, and compatibility with various organic materials, isobutanol plays an important role in industrial chemical production. It is particularly valuable in formulations where solvent performance, evaporation characteristics, and compatibility with resins and other organic compounds are important.

For manufacturers and distributors, stable-quality industrial-grade isobutanol is an important raw material for continuous production and formulation processes.

Storage and Transportation

Isobutanol is a flammable liquid and should be stored in a cool, dry, and well-ventilated area, away from heat, sparks, open flames, and strong oxidizing agents. Containers should be tightly closed and protected from ignition sources.

During loading, unloading, storage, and transportation, appropriate fire prevention, anti-static, ventilation, and leakage-control measures should be implemented in accordance with applicable safety regulations and transportation requirements.

Isobutanol Supplier China

For international buyers, selecting a reliable Isobutanol supplier in China is important for maintaining consistent product quality and stable supply. Buyers typically evaluate purity, product specifications, packaging, supply capacity, lead time, COA, SDS, and international export experience when sourcing isobutanol in bulk.

Chinese chemical suppliers can provide isobutanol in different packaging and shipment options according to customer requirements, supporting both regular industrial procurement and long-term chemical supply.
