n-butylamine 99.9 +% extra pure

What is Butylamine?

n-Butylamine is a chemical compound produced in the chemical and pharmaceutical industries as an intermediate in the synthesis of organic substances. It is a primary amine. n-Butylamine belongs to the group of aliphatic amines, more specifically the butylamines, and is isomeric for isobutylamine, sec-butylamine and tert-butylamine.

The common name Norvalamin is derived from the amino acid Norvaline. Decarboxylation of norvaline produces n-butylamine.

n-Butylamine is formed when n-butanol or n-butanal is reacted with ammonia in the presence of catalysts. It can also be generated from valeric acid by the so-called Schmidt reaction.

n-Butylamine forms highly flammable vapour-air mixtures. The compound has a flash point at −14 °C. The explosion range is between 1.7 volume percent (50 g m - 3) as lower explosive limit (LEL) and 10 volume percent (304 g m - 3) as upper explosive limit (UEL) . The maximum gap width was determined to be 0.92 mm. This results in an assignment to explosion group IIA. The ignition temperature is 310 ° C. The substance therefore falls into temperature class T2.

What is Butylamine used for?

n-Butylamine is an intermediate in the production of various organic compounds such as dyes, drugs, pesticides, plasticizers, emulsifiers, anti-corrosion agents and adhesives and can be used as a solvent in titration.
