Isobutylamine is a chemical compound selected from the group of aliphatic amines. It is a primary amine and one of the four isomeric amines (along with tert-butylamine, n- butylamine, and sec - butyl ) butane.

Occurrence

Isobutylamine occurs naturally in some algae and plants.

Production and representation

Isobutylamine can be represented by the reaction of isopropanol with ammonia and hydrogen.

Properties

Isobutylamine is a colorless liquid, boiling at atmospheric pressure at 66 ° C. The vapor pressure function is given by Antoine corresponding log10 (P) = A- ( B / ( T C)) (P in Pa, T in K ) with A = 5.9, B = 1051 and C = -70 in the temperature range of 248-347 K. The compound forms flammable vapor - air mixtures. It has a flash point of -13 ° C. The explosive range is between 1.9 vol% (57 g/m3) as the lower explosive limit ( LEL) and 10.8 % by volume (330 g/m3 ) and upper explosive limit (UEL ). The ignition temperature is 370 ° C. The fabric falls within the temperature class T2.

The aqueous solution of isobutyl amine reacts strongly alkaline.

Use

Isobutylamine is used to a limited extent for organic syntheses and in insecticides.

Safety

Nitrozating agents may lead to the formation of carcinogenic substances.
