Trioctylamine CAS 1116-76-3

Trioctylamine (CAS 1116-76-3) is a high-molecular-weight tertiary amine commonly supplied as a liquid for industrial applications requiring selective extraction, phase transfer, or amine-based reactivity. It is primarily used in hydrometallurgical solvent extraction systems, acid recovery processes, and as an intermediate in organic synthesis.

From a supply perspective, Trioctylamine is typically delivered in liquid form suitable for direct use in industrial formulations or processing systems. Standard export packaging is available, with documentation such as COA, TDS, and SDS provided to support procurement and handling requirements.

Typical Applications

Hydrometallurgical extraction: Used as an extractant in solvent extraction systems for recovery and separation of metals such as uranium, rare earth elements, and other metal ions.
Acid recovery systems: Applied in extraction of mineral acids (e.g., hydrochloric acid, sulfuric acid) from aqueous streams.
Chemical intermediate: Utilized in the synthesis of quaternary ammonium compounds and other amine derivatives.
Phase transfer and separation processes: Functions as an organic phase component in liquid-liquid extraction systems.

Packaging

Trioctylamine is supplied as a liquid and is typically packed in clean, sealed drums or intermediate bulk containers (IBC) suitable for liquid chemical transport. Packaging materials are selected to ensure compatibility with amine-based substances and to prevent contamination during storage and handling.

For export supply, containers are prepared to maintain product integrity during long-distance transportation. Packaging arrangements may be adjusted based on order quantity and logistical requirements.

Storage

Store in a cool, well-ventilated area away from direct sunlight and sources of heat or ignition. Containers should be kept tightly closed to avoid contact with air and moisture. Proper handling procedures should be followed to maintain product stability and prevent contamination during storage and transfer.
