This colourless liquid is one of the four isomeric amines of butane, the others being sec-butylamine, tert-butylamine, and isobutylamine. 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. Synthesis and reactionsIt is produced by the reaction of ammonia and alcohols over alumina: CH3(CH2)3OH + NH3 → CH3(CH2)3NH2 + H2On-Butylamine exhibits reactions typical of other simple alkyl amines, i.e. protonation, alkylation, acylation, condensation with carbonyls. Like other simple aliphatic amines, n-butylamine is a weak base: the pKa of [CH3(CH2)3NH3]+ is 10.78.[3]n-Butylamine is also a commonly used ligand in coordination chemistry, which can coordinate with metal ions, such as Pt2+, Pd2+ ions, and form tetrabutylamine- or dibutylamine- metal complexes.[4][5] UsesThis 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'-dibutylthiourea, a rubber vulcanization accelerator, and n-butylbenzenesulfonamide, a plasticizer of nylon. It is used in the synthesis of Fengabine, the fungicide benomyl, and butamoxane, and the antidiabetic Tolbutamide.[6] SafetyThe LD50 to rats through the oral exposure route is 366 mg/kg.[7] In regards to occupational exposures to n-Butylamine, the Occupational Safety and Health Administration and National Institute for Occupational Safety and Health have set occupational exposure limits at a ceiling of 5 ppm (15 mg/m3) for dermal exposure.[8] References1. ^1 {{IDLH|109739|N-Butylamine}} {{DEFAULTSORT:Butylamine, n-}}2. ^1 2 {{PGCH|0079}} 3. ^{{cite journal|author=H.
