Description

Trans-2-Hexene (CAS 4050-45-7), also known commercially as Orgal F 4050, is a linear alpha-olefin isomer used as a reactive monomer and process solvent in petrochemical and polymer manufacturing. It serves as a building block in synthesis chains where controlled chain length and double-bond positioning are critical to end-product performance in various industrial sectors.

In polyolefin production, it functions as a comonomer to modify the density and mechanical properties of polyethylene grades used in film, pipe, and packaging applications. Refinery and gas processing operations use it as a reference compound and process intermediate in alkylation and isomerization units to ensure high-quality chemical output.

In industrial and institutional cleaning formulations, it contributes to solvent blends targeting hydrocarbon-based soils and residues where fast evaporation and low polarity are requirements. Specialty chemical synthesis also draws on it as a C6 olefin intermediate for producing plasticizers, lubricant additives, and surfactant precursors for global manufacturing chains.

The product is supplied as a clear liquid, typically in drum, IBC, and bulk tanker quantities suited to industrial procurement volumes and large-scale logistics operations. Technical-grade is the standard commercial specification, with purity levels commonly ranging from 97% upward depending on specific application requirements and catalyst testing needs.
