n-Butanol stands for normal butanol and may be short named as NBA.

n-Butanol is a clear, colorless liquid that is flammable with a characteristic banana-like odor

n-Butanol may also be called n-butyl alcohol or 1-Butyl alcohol or Butanolen or Butanol


n-Butanol demonstrates an overall low order of toxicity.

Market literature classifies n-butanol as both an oxo-chemical derivative and a plasticizer alcohol for market purposes.

The uses of n-butanol vary by geographic area, but in general it is used to make other chemicals, or used as a solvent or an ingredient in formulated products such as cosmetics.

 – Acrylate esthers and methacrylate esters

 – Glycol ethers

 – n-Butyl acetate

 – Amino resins

 – n-Butylamines

The manufacturing process first generates n-butyraldehyde using propylene, carbon monoxide (CO) and hydrogen gas (H2) as feedstock.

By using low-pressure technology and a triphenylphosphine rhodium hydrocarbonyl catalyst, approximately eight to ten times more n-butyraldehyde is produced than isobutyraldehyde.

The n-butyraldehyde is then reacted with H2 to form n-butanol and Isobutanol as a by-product.

One of the most important application in using n-Butanol and its derivatives is the water-based coatings formulations of all kinds.

Analysts estimate that nearly 70 percent of all exterior architectural paints and as much as 85 percent of interior paints are now water-based.

For butanol, butyl acrylate and butyl acetate, become increasingly important in following uses:

 – Solvent for paints, coatings, varnishes, resins, gums, dyes, camphor,  vegetable oils, dyes, fats, waxes, resins, shellac,  rubbers, and alkaloids.

 – Solvent in the purification of polyolefins, Alkyd resin coatings

 – Intermediate in manufacturing other chemicals, esters of herbicides pharmaceuticals, veterinary medicine

 – Swelling agent in textiles

 – Manufacturing safety glass, hydraulic fluids, and detergent formulations.

 – Formulating brake fluids.

 – Extractant in manufacturing antibiotics, vitamins, and hormones

 – Manufacturing garments from polyvinyl butyral-coated fabric,

 – Cement additive to increase the fineness

 – Ore floatation agents

 – Melamine formaldehyde resins
