n-Butanol or n-butyl alcohol or normal butanol is a primary alcohol with a 4-carbon structure. n-Butanol is an intermediate in the production of butyl acrylate, butyl acetate, dibutyl phthalate, dibutyl sebacate, and other butyl esters, and the corresponding butyl ether acetates. Other industrial uses include the manufacture of pharmaceuticals, polymers, pyroxylin plastics, herbicide esters, printing and butyl xanthate. It is also used as a diluent/reactant in the manufacture of urea–formaldehyde and melamine–formaldehyde resins. The intermediates in the production of n-butanol are n-butyraldehyde and isobutyraldehyde.
