Hexylamine (more precisely n -hexylamine) is a chemical compound from the group of aliphatic amines . It is also a primary amine.

Presentation and extraction

Hexylamine can be obtained by reacting 1-hexanol or 1-hexyl halides with ammonia .

{\ displaystyle \ mathrm {C_ {6} H_ {13} OH + NH_ {3} \ rightarrow C_ {6} H_ {13} NH_ {2} + H_ {2} O}}

{\ displaystyle \ mathrm {C_ {6} H_ {13} X + NH_ {3} \ rightarrow C_ {6} H_ {13} NH_ {2} + HX \ X = Cl, Br}}

A further preparation can be done by hydrogenation of Hexylonitril done.

{\ displaystyle \ mathrm {C_ {5} H_ {11} CN + H_ {2} \ rightarrow C_ {6} H_ {13} NH_ {2}}}

properties

Hexylamine is a flammable, volatile, colorless liquid with an amine-like odor, which is sparingly soluble in water. It decomposes when heated, producing nitrogen oxides , nitrous gases and nitrosamines . Your aqueous solution reacts strongly alkaline.

use

Hexylamine is used as an intermediate in the manufacture of rubber chemicals , pharmaceuticals, and dyes .

safety instructions

Hexylamine vapors can form an explosive mixture with air. The compound has a flash point of 27 ° C. The explosion range is between 2.1 vol.% As the lower explosion limit (LEL) and 9.3 vol.% As the upper explosion limit (UEL).
