TRIOCTYLAMINE

Trioctylamine is a clear and colorless chemical compound in the group of aliphatic amines and tertiary amines.
Trioctylamine is a clear colorless method and can be converted to the amine hydrochloride etherate which is recrystallized four times from diethyl ether at -30 °C. 
Neutralization of Trioctylamine regenerates the free amine which distilled under high vacuum.

Application of Trioctylamine
Trioctylamine is used to extract organic acids such as succinic acid and acetic acid, and also precious metals. 
A formulation containing metoxuron mixed with an emulsion containing trioctylamine 50%, atlox 4851 B 15%, and isopropanol 35% was active as a potato defoliant. 
Trioctylamine can be used to extract monocarboxylic acid for equilibria and correlation of apparent reactive equilibrium constant.
Liquid-liquid equilibria for aqueous solutions of carboxylic acids with trioctylamine in various diluents was determined at various trioctylamine concentrations. 
The loading of trioctylamine for a given carboxylic acid depends on the nature of the solute and its concentration. 
The apparent extraction equilibrium constants depend on the hydrophobicity and acidity of the carboxylic acid, as well as the specific basicity of trioctylamine.
Trioctylamine production can be used as a mineral extraction reagent, an extractant for reactor fuel processing, and its use as an extractant for identification of dyes may result in its release to the environment through various waste streams.

Trioctylamine Usage

-Used in extraction of rare and noble metal.In hydro-chloride solvent,it can separate Cobalt and Nickel,and is also used in extracting Wolfram,Molybdenum,Vanadium,Platinum,Gold and Copper.
-Trioctylamine is also used in treatment of industrial waste water by complexing extraction,especially used in treatlnent of the water containing organic acids and este rs.

Trioctylamine is used as an extractant for organic acids and precious metals.

Properties of Trioctylamine:
Trioctylamine can treat wastewater containing organics in sewage treatment plants, especially phenolic compounds and acidic organics containing benzene rings.
Trioctylamine can also undergo quaternization to form a quaternary ammonium salt, which is used for precious metal extraction and phase transfer catalyst, and can also be used as an extractant for pharmaceutical intermediates.
Trioctylamine can be used as an extractant to extract precious metals such as lanthanide, nickel, cobalt, actinium, etc. in the extraction of precious metals, and is also used in the rare earth industry.
Trioctylamine can also be used as a metal anticorrosion agent and detergent for metal surface treatment.
