Description and Uses

n-Butyl alcohol is a colourless flammable liquid with strong alcoholic odour. n-Butyl alcohol is a highly refractive liquid and burns with a strongly luminous flame. It is incompatible with strong acids, strong oxidising agents, aluminium, acid chlorides, acid anhydrides, copper, and copper alloys. n-Butyl alcohol has an extensive use in a large number of industries. For instance, it is used as solvent in industries associated with the manufacturing of paints, varnishes, synthetic resins, gums, pharmaceuticals, vegetable oils, dyes, and alkaloids. n-Butyl alcohol finds its use in the manufacture of artificial leather, rubber, plastic cements, shellac, raincoats, perfumes, and photographic films.

As solvent for fats, waxes, resins, shellac, varnish, gums etc.; manufacture of lacquers, rayon, detergents, other butyl Compounds; in microscopy for preparing paraffin imbedding materials.
