Chemical compound
n amine ) with the formula CH3 CH 2 3 NH 2 isomeric amines of butane , the others being sec -butylaminetert -butylamineisobutylamine . It is a liquid having the fishy, ammonia-like odor common to amines. The liquid acquires a yellow color upon storage in air. It is soluble in all organic solvents. Its vapours are heavier than air and it produces toxic oxides of nitrogen during combustion.[3]
Synthesis and reactions
[ edit ]
It is produced by the reaction of ammonia and alcohols over alumina :
CH 3 CH 2 3 3 3 CH 2 3 NH 2 2 O
n weak base . The pKa CH 3 CH 2 3 NH 3 + is 10.78.[4]
n cis - and trans -[PtI2 NH 2 Bu )2 [5]
Uses
[ edit ]
This compound is used as an ingredient in the manufacture of pesticides (such as thiocarbazides ), pharmaceuticals , and emulsifiers . It is also a precursor for the manufacture of N N vulcanization accelerator, and n plasticizer of nylon . It is used in the synthesis of fengabine , the fungicide benomyl , and butamoxane , and the antidiabetic tolbutamide .[6]
Butylamine is a precursor to the fungicide benomyl .
