Definition
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
Comments
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
