nButylamine

n-Butylamine, also known as 1-aminobutane, is an organic amine with the formula C4H11N. It is a primary aliphatic amine consisting of a straight four-carbon chain bearing an amino group (CH3–CH2–CH2–CH2–NH2). It appears as a colorless liquid at room temperature and has a characteristic ammonia-like odor. It is miscible with water and with many organic solvents, and it is relatively volatile.

Production and synthesis: Industrially, n-butylamine is mainly produced by hydrogenation of butanenitrile, which is derived from butenes, or by reductive amination of butyraldehyde with ammonia. Other routes include alkylation of ammonia with butyl halides under suitable conditions. The method chosen depends on scale, cost, and purity requirements.

Uses: It serves as a chemical intermediate in the synthesis of a variety of compounds, including N-substituted amines, amides, and other nitrogen-containing chemicals. It is used in the manufacture of surfactants, rubber accelerators, dyes, pharmaceuticals, and agricultural chemicals, as well as in polymer and coating applications.

Safety: n-Butylamine is a corrosive irritant and a potential toxin. It can cause burns to skin and eyes and respiratory irritation if inhaled. It is flammable and should be handled in a well-ventilated area with appropriate PPE, stored away from oxidizers, and contained to prevent leaks. Spill response and waste disposal should follow applicable regulations.
