Description and Uses

n-Butylamine is one of the four isomeric amines of butane, the others being sec-butylamine, tert-butylamine, and isobutylamine. It is a colourless to yellow liquid and is highly flammable. It is stable and incompatible with oxidising agents, aluminium, copper, copper alloys, and acids. n-Butylamine finds its uses in the manufacture of pesticides (such as thiocarbazides), pharmaceuticals, and emulsifiers. It is also a precursor for the manufacture of N,N′-dibutylthiourea, a rubber vulcanisation accelerator, and n-butylbenzenesulphonamide, a plasticiser of nylon.

n-Butylamine is used as an intermediatefor various products, including dyestuffs,pharmaceuticals, rubber chemical, synthetictanning agents, and emulsifying agents. It isused for making isocyanates for coatings.
