Reference Information

use	as a precious metal extractant. In the metallurgical industry, it is used to extract and separate cobalt, nickel, actinides and lanthanides. It is used in organic synthesis. It is a heat-resistant, solvent-resistant, polymeric rubber antioxidant. It is the intermediate amine extractant for synthesizing NAPM. It has good extraction performance for actinides such as thorium and uranium. Moreover, it can extract and separate non-ferrous metals, rare and scattered metals and platinum elements in different systems. Used in the production of phase transfer catalysts, rubber additives and corrosion inhibitors. Used as surfactant and extractant
Production method	Ammoniation is carried out in the presence of aluminum trichloride catalyst using n-octanol as raw material. The reaction is carried out in a condensation kettle, ammonia is introduced into the kettle, and the reaction is carried out at 400 ℃. Then remove the excess n-octanol and filter out the catalyst to obtain the finished trioctylamine. Raw material consumption (kg/t) n-octanol 1217 trialumina 685
spontaneous combustion temperature	315°C
