Description

Alkenes, C20-24 α- is a defined mixture of long-chain linear α-olefins, primarily in the C20 to C24 carbon range. This product is valued for its role as a versatile chemical intermediate and performance additive in advanced manufacturing. It is particularly essential for industries requiring high-purity hydrocarbon feedstocks for synthesis or specific hydrophobic properties. The CAS number for this compound is 93924-10-8.

Application

• Lubricant and Synthetic Oil Additives: Acts as a key feedstock for producing polyalphaolefins (PAOs) and other high-performance synthetic base stocks.
• Surfactant and Detergent Intermediates: Used in the manufacture of linear alkylbenzene sulfonates (LAS) and other surfactants for industrial and household cleaners.
• Polymer Comonomer: Serves as a comonomer in the production of linear low-density polyethylene (LLDPE) and other specialty polyolefins to modify properties.
• Chemical Synthesis: Provides a defined hydrocarbon chain for organic synthesis, including the production of amines, alcohols, and other functionalized derivatives.
• Paper Sizing Agents: Utilized in the production of alkyl ketene dimer (AKD), a common internal sizing agent for paper and cardboard.
• Specialty Fluids and Plasticizers: Employed in formulating specialty fluids, process oils, and as intermediates for certain plasticizers.

Quality Control

Our Alkenes, C20-24 α- is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency and meets defined specifications for composition, purity, and key physical properties. Certificates of Analysis (COA) detailing assay, chain length distribution, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its properties of being highly volatile and easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) to minimize degradation and maintain product integrity. Keep away from strong oxidizing agents.
