sec -Butylamine is a chemical compound from the group of aliphatic amines . It is a primary amine and isomeric to n -butylamine , isobutylamine and tert -butylamine . sec -Butylamine is in the form of a colorless, volatile and highly flammable liquid.
history
sec -Butylamine was used as a fungicide for citrus fruits in the 1960s after detailed studies of its effects (Eckert and Kolbezen, 1962) .
properties
The vapors are 2.5 times as heavy as air.
Sec-butylamine forms highly flammable vapor-air mixtures. The compound has a flash point of −20 ° C. The explosion range is between 1.7% by volume (50 g / m 3 ) as the lower explosion limit (LEL) and 9.7% by volume (295 g / m 3 ) as the upper explosion limit (UEL). The ignition temperature is 290 ° C. The substance therefore falls into temperature class T3.
Stereoisomeric forms
sec -Butylamine occurs in two stereoisomeric forms [( R ) - or ( S ) - sec -Butylamine].
Whenever " sec -Butylamine" is mentioned in this article or in the scientific literature without additional information on the configuration , the racemate [more precisely ( RS ) - sec -Butylamine or (±) - sec -Butylamine] is meant.
use
sec -Butylamine is used as an intermediate in the synthesis of various organic compounds and as a fungicide .
safety instructions
The vapors of sec -butylamine form an explosive mixture with air. Its flash point is −20 ° C.
