1-Octadecene

CAS: 112-88-9

Overview

1-Octadecene (CAS 112-88-9 ) is a long-chain linear alpha-olefin used as a chemical building block and functional fluid across specialty chemical manufacturing. Its terminal double bond makes it a reactive intermediate for polymer synthesis and surface modification.

In plastics and polymer manufacturing, it serves as a comonomer in polyethylene and polyalphaolefin production, influencing molecular weight distribution and end-product flexibility. This versatility is essential for modern industrial applications.

Personal care formulators incorporate it into emollient systems and carrier bases where a non-polar, low-viscosity fluid is needed to improve skin feel. It is also utilized in lubricant and metalworking formulations as a base fluid component.

The chemical functions as a synthetic intermediate for high-performance gear oils and cutting fluids. Upstream oil and gas operations use it as a process chemical in drilling fluid formulations requiring thermal stability at elevated temperatures.

1-Octadecene is supplied as a clear liquid, typically in drum and IBC quantities with bulk availability for large-scale industrial buyers. Technical grade is the standard commercial offering for most industrial processes.

Purity levels commonly range from 90% to 97%+ depending on application requirements. Higher-purity cuts are available for specialty polymer and fine chemical synthesis where olefin content and isomer profile are critical to process consistency.
