1-Octene (CAS 111-66-0) is a fundamental chemical compound in the petrochemical and fine chemical industries, valued for its unique properties and versatile applications. As a linear alpha-olefin (LAO), it possesses a terminal double bond that makes it highly reactive and suitable for a wide range of chemical transformations. This article provides an overview of 1-Octene, including its key characteristics, primary uses, and essential considerations for sourcing this critical material from reliable manufacturers.

Key Properties of 1-Octene:

1-Octene is a colorless, clear liquid with a characteristic gasoline-like odor. Its chemical formula is C8H16, and it has a molar mass of approximately 112.24 g/mol. Key physical properties include:

  • Appearance: Clear, colorless liquid
  • Boiling Point: Approximately 121-123 °C
  • Melting Point: Approximately -101.7 °C
  • Density: Around 0.715 g/cm³ at 25 °C
  • Flash Point: Approximately 21 °C (70 °F), indicating it is a flammable liquid.
  • Solubility: Miscible with most organic solvents, but poorly soluble in water.

Its structure as a linear alpha-olefin, with the double bond at the primary position, imbues it with specific reactivity patterns advantageous in polymerization and other chemical reactions.

Major Applications of 1-Octene:

The industrial significance of 1-Octene is multifaceted:

  1. Polyethylene Comonomer: This is perhaps the largest application. 1-Octene is used as a comonomer in the production of LLDPE and HDPE. Its incorporation leads to enhanced properties such as improved flexibility, tear strength, impact resistance, and melt strength, crucial for film applications, pipes, and molded products.
  2. Organic Synthesis: 1-Octene serves as a key intermediate in the synthesis of various organic compounds. It is used to produce linear aldehydes (like nonanal) via hydroformylation, which are then further processed into nonanoic acid. Nonanoic acid and its derivatives find use in lubricants, plasticizers, and surfactants.
  3. Plasticizers and Surfactants: As mentioned, derivatives of 1-Octene are essential components in the manufacture of plasticizers that increase polymer flexibility and surfactants used in detergents and emulsifiers.
  4. Analytical Standards: Due to its well-defined purity and structure, 1-Octene is often employed as a standard in gas chromatography (GC) and other analytical techniques for calibration and testing purposes.

Sourcing 1-Octene from Reliable Suppliers:

For businesses that rely on 1-Octene, ensuring a consistent supply of high-purity material is vital. When seeking to buy 1-Octene, consider the following:

  • Purity Levels: For most applications, especially in polyethylene production, high purity (99%+) is essential. Always verify the purity specifications and ensure they meet your requirements.
  • Manufacturer Reputation: Partnering with established manufacturers, particularly those in China known for their production capacity and adherence to international quality standards, is recommended.
  • Technical Support and Documentation: Reliable suppliers will provide comprehensive technical data sheets (TDS), safety data sheets (SDS), and certificates of analysis (CoA) upon request.
  • Pricing and Logistics: Compare quotes from different suppliers, considering not only the per-unit price but also the logistics, packaging options (e.g., drums, ISO tanks), and delivery timelines.
