n-Butyl Alcohol (n-Butanol)

n-Butyl alcohol (n-butanol, CAS 71-36-3) is a clear, colorless liquid used as a solvent in coatings, printing inks and adhesives. It is also a raw material for producing n-butyl acetate, n-butyl acrylate and other butyl derivatives.

Applications

1. Coatings, Paints and Printing Inks

n-Butanol is used in solvent blends for industrial paints, varnishes and printing inks. In compatible resin systems, it helps adjust viscosity and evaporation rate, giving the wet film time to flow and level before it dries.

2. Chemical Manufacturing

n-Butanol reacts with acetic acid to produce n-butyl acetate, an ester solvent, and with acrylic acid to produce n-butyl acrylate, a monomer for acrylic polymers. It is also a feedstock for selected plasticizers, glycol ethers and modified resins.

3. Adhesives and Sealants

In selected solvent-based adhesives and sealants, n-butanol acts as a co-solvent. Formulators use it to adjust application viscosity and drying time. Compatibility and bond performance depend on the resin, substrate and complete solvent blend.

4. Fine Chemical Processing

n-Butanol can serve as a reaction medium or extraction solvent in selected manufacturing processes. For applications with tight impurity limits, review the water and acidity specifications when selecting a grade.

5. Industrial Cleaning and Degreasing

n-Butanol can be included in formulated cleaners for removing oily residues from compatible equipment and surfaces. Evaluate the complete cleaner on the intended substrate before use, particularly on plastics and coated parts.

Packaging, Storage and Handling

Packaging options include drums, IBCs and ISO tanks, depending on the order and shipment.

n-Butanol is a flammable liquid and can cause serious eye damage. Store it in tightly closed, compatible containers in a cool, well-ventilated area, away from ignition sources and strong oxidizers. Use suitable gloves and eye protection, and follow the safety data sheet (SDS) for handling and transfer.

Frequently Asked Questions

Are n-butyl alcohol, n-butanol and 1-butanol the same?

Yes. These names refer to the straight-chain alcohol identified by CAS 71-36-3.

Is n-butanol the same as isobutanol?

They are different isomers. n-Butanol has a straight carbon chain, while isobutanol is branched and has CAS 78-83-1.

Is n-butanol miscible with water?

It has limited water solubility, about 7.7 g per 100 mL at 20 °C. Check the composition of water-containing blends for phase separation.

What is the difference between n-butanol and n-butyl acetate?

n-Butanol is an alcohol (CAS 71-36-3). n-Butyl acetate is an ester (CAS 123-86-4) that can be made from n-butanol. They have different solvent properties.
