Application of Octadecylamine Octadecylamine in thermal system,
also known as thin film amine, is a film-like solid at room temperature, and its decomposition temperature is above 450 ℃. After adding the thermal system, it will be gasified at high temperature. The system forms a hydrophobic protective film on the metal surface to isolate the air from the metal, thereby preventing the corrosion of the metal by water and atmospheric oxygen and carbon dioxide.

Application in flotation
Octadecylamine as a cationic collector in flotation, but also has a certain foaming effect. When Octadecylamine is used as a flotation agent, because it is insoluble in water, many people who are exposed to flotation for the first time do not know how to use it. There are two ways to use it: one is to use dilute hydrochloric acid to make it into salt, and the other is It is boiled in water and added to the flotation machine while it is hot for flotation.

Uses
organic synthesis, corrosion inhibitor, emulsifier. Widely used as a corrosion inhibitor for boilers and pipelines in various power plants
The shelf life of stored Octadecylamine emulsion is half a year, sealed and stored at 4-40 degrees
