2-Octene[2]

Updated: 2026-09-30

Overview

2-Octene is an eight-carbon alkene with a double bond at the second position. As a member of the olefin family, it serves as a versatile intermediate in chemical manufacturing. Industrial production methods typically involve petroleum refining byproducts or catalytic cracking processes. Unlike its isomer 1-octene, 2-octene's internal double bond makes it less reactive in some polymerization applications but valuable for producing branched derivatives. Commercial grades often contain mixtures of cis- and trans-isomers, with purity levels tailored to specific industrial uses.

Physical and Chemical Properties

With a boiling range of 122-125°C, 2-octene is classified as a volatile organic compound (VOC). Its density of about 0.72 g/cm³ makes it lighter than water, consistent with hydrocarbon characteristics. The compound exhibits typical alkene reactivity, participating in addition and oxidation reactions. Notable chemical behaviors include hydrogenation to octane, halogenation reactions, and participation in olefin metathesis. The double bond's reactivity makes it useful for creating longer-chain compounds or functionalized derivatives. Thermal stability allows for storage and transport under nitrogen at ambient temperatures when properly inhibited.

Main Applications

In polymer production, 2-octene acts as a co-monomer to modify polyethylene properties, increasing flexibility and impact resistance. The petrochemical industry utilizes it for alkylation processes and synthetic lubricant formulations where branching improves low-temperature performance. Specialty chemical manufacturers employ 2-octene as a precursor for plasticizers, surfactants, and synthetic alcohols. Research applications include studies of catalytic reactions and as a model compound for developing new olefin transformation technologies. The compound's balanced properties between volatility and reactivity make it particularly useful for laboratory-scale organic synthesis.

Safety and Storage

As a Category 3 flammable liquid, 2-octene requires storage in approved containers with proper grounding to prevent static discharge. Secondary containment is recommended due to potential environmental hazards if spilled. Ventilation should maintain vapor concentrations below 10% of the lower explosive limit (LEL). Personal protective equipment including chemical goggles, impervious gloves, and flame-resistant clothing is advised during handling. Fire suppression requires dry chemical, CO2, or foam - water may be ineffective and spread the fire. Decomposition products from combustion include toxic carbon monoxide and acrid smoke.

B2B Procurement Guide

Industrial buyers should specify required isomer ratios (cis/trans) and purity levels, typically 95-99% for most applications. Bulk shipments commonly occur in isotanks (20-25 metric tons) or drums (200kg), with pricing structures offering discounts for full truckload quantities. Reputable suppliers provide certified analysis reports including moisture content, inhibitor levels (when applicable), and residual catalyst measurements. Just-in-time delivery arrangements are preferable to minimize storage risks. Technical support for handling and regulatory documentation should be confirmed during supplier evaluation.
