n-Butyl Alcohol (alias of n-Butanol)

CAS RN: 71-36-3

Major Uses

... is employed as a solvent for paints, lacquers & varnishes, natural & synthetic resins, gums, vegetable oils, dyes & alkaloids. It is used as an intermediate in the manufacture of pharmaceuticals & chemicals, & employed in industries producing artificial leather, textiles, safety glass, rubber cement, shellac, raincoats, photographic films & perfumes.
BA is used primarily as an industrial intermediate in the production of ethers and butyl ether acetates, pharmaceuticals, polymers and plastics. BA is used to a lesser extent as a solvent, reactant/diluent and component in consumer (nail polish formulations, rubber cement and safety glass) and industrial products.
As organic solvent for fats, waxes, resins, shellac, varnish gums, etc.; manufacture lacquers, rayon, detergents, other butyl compounds; in microscopy for preparing paraffin imbedding materials.
n-Butyl Alcohol is a primary aliphatic alcohol historically used as a solvent in nail care cosmetic products, but new concentration of use data indicate that it also is being used at low concentrations in eye makeup, personal hygiene, and shaving cosmetic products. n-Butyl Alcohol has been generally recognized as safe for use as a flavoring substance in food and appears on the 1982 Food and Drug Administration (FDA) list of inactive ingredients for approved prescription drug products...
Chem int for ethylene glycol monobutyl ether, plasticizers incl dibutyl phthalate; chem int for butylamines, 2,4-d esters
Preparation of esters, especially butyl acetate; solvent for resins and coatings; plasticizers; dyeing assistant; hydraulic fluids; detergent formulations; dehydrating agent (by azeotropic distillation); intermediate; "butylated" melamine resins; glycol ethers; butyl acrylate.
The largest volume commercial derivatives of 1-butanol in the US are n-butyl acrylate and methacrylate which are used principally in emulsion polymers for latex paints, in textile applications and in impact modifiers for rigid poly(vinyl chloride). Butyl glycol ethers, the largest volume derivatives of n-butyl alcohol, are used in solvent applications. 1-Butanol is used as a direct solvent in paints and other surface coatings. It acts synergistically with butyl acetate as a latent solvent system for nitrocellulose lacquers and thinners to give a solvent system stronger than either solvent alone. Other direct solvent applications for n-butyl alcohol are in the formulation of pharmaceuticals, waxes, and resins. Additional commercial markets for 1-butanol include plasticizer esters (eg, dibutyl phthalate), butylated melamine-formaldehyde resins, and mono-, di-, and tributylamines.
1-Butanol is used principally in the field of surface coating. In the US, approximately 85% of 1-butanol production finds an outlet in this market. It is used either directly as a solvent for varnishes, or it is converted into derivatives, which then serve as solvents or monomer components. In the US, 1-butanol is used for the manufacture of butylamines. 1-Butanol has numerous applications in the plastics and textile sector. It is used as a coagulation bath for spinning acrylic fibers and in the dyeing of poly(vinyl alcohol) fibers.
Application in surface coatings; in adhesive & as a solvent adhesive in the manufacture of garments from polyvinyl butyral coated fabric; in the manufacture of derivatives of butyl alcohol, incl chemicals, herbicides, ore flotation agents, urea & melamine formaldehyde resins, & pharmaceuticals. Denatured alcohol, a swelling agent in textiles, is also used as an azeotrophic dehydrating agent & blending agent in laboratory analysis.
