Read： 720 Time：16months ago Source：Transform the World with Simplicity

Octylamine and n-octylamine are two common organic amine compounds, which are widely used in many fields. Octylamine and n-octylamine are different in chemical structure, but also have unique features in function and properties. The molecular formula of

octylamine is C8H19N, which is a fatty amine compound. Octylamine can be obtained by introducing an amino group in n-octane. Because of its long molecular chain, octylamine has a higher boiling point and lower vapor pressure, so it is widely used in many fields. Octylamine is mainly used in softener, surfactant, rubber formulation, etc. In addition, octylamine also has excellent dispersibility and wettability, so it is often used as an auxiliary agent.

n-octylamine has the formula C8H19NH2, which is an isomer of a fatty amine. n-octylamine is prepared in a manner similar to octylamine by introducing an amino group into n-octane. Compared with octylamine, n-octylamine has a higher vapor pressure due to its shorter molecular chain. N-octylamine has good surface activity and wettability, so it is often used in various surface coatings, inks, adhesives and other fields. At the same time, n-octylamine can also be used as an additive for petroleum anti-gas rust agent and cleaning agent to enhance the wetting ability.

In summary, octylamine and n-octylamine are different in chemical structure, function and properties. Because of its long molecular chain, high boiling point and low vapor pressure, octylamine is widely used in softener, surfactant and other fields. N-octylamine, on the other hand, is commonly used in coatings, inks and other industries due to its shorter molecular chain, better surface activity and wettability. No matter in which field, octylamine and n-octylamine have played an important role and contributed to the development of the chemical industry.
