Rubber antioxidant Surfactants Tri-n-octylamine CAS 1116-76-3 Precious metal extractants

Introduction:

Trioctylamine is referred to as "TOA". It is an important tertiary amine extractant. Molecular formula C24H51N. Molecular weight 353.6. Colorless viscous oily liquid. It has a pungent odor. Specific gravity 0.8110. Boiling point 180-202℃ (400 Pa). Refractive index 1.4449. It is difficult to dissolve in water, but easily soluble in organic solvents. Commonly used diluents are toluene and xylene. It can be prepared by oxidation of octyl bromide. Trioctylamine is one of the commonly used excellent extractants in analytical chemistry and radiochemistry. In metallurgy, it is used to extract and separate precious metals such as cobalt, nickel, actinium, lanthanum, etc. It is widely used in the separation and determination of neptunium and plutonium in nuclear fuel and fission products.

Uses:

Amine extractants have good extraction performance for actinide elements such as thorium and uranium, and can extract and separate non-ferrous metals, rare and scattered metals and platinum elements under different systems. Used in the production of phase transfer catalysts, rubber additives and corrosion inhibitors. Used as a precious metal extractant. In the metallurgical industry, it is used to extract and separate cobalt, nickel, actinide and lanthanide elements. Used in organic synthesis, it is a heat-resistant, solvent-resistant, polymerized rubber antioxidant, and an intermediate for the synthesis of NAPM.
