Description

Undecene is a versatile linear α-olefin with the CAS number 28761-27-5, serving as a crucial intermediate in the synthesis of a wide range of specialty chemicals. Its terminal double bond makes it highly reactive, enabling its use in polymerization, alkylation, and functionalization reactions. This product is essential for manufacturers in the fragrance, lubricant, surfactant, and pharmaceutical industries seeking to create high-value derivatives.

Application

• Fragrance and Flavor Intermediates: Used in the synthesis of aldehydes, alcohols, and esters that serve as key aroma chemicals.
• Lubricant and Fuel Additives: Acts as a precursor for polyalphaolefins (PAOs) and other performance additives that enhance viscosity and thermal stability.
• Surfactant and Detergent Manufacturing: Employed in the production of linear alkylbenzene sulfonates (LAS) and other biodegradable surfactants.
• Polymer and Copolymer Production: Serves as a comonomer in the manufacture of polyethylene and other polyolefins to modify properties.
• Organic Synthesis: A valuable building block for pharmaceuticals, agrochemicals, and fine chemicals via hydroformylation, epoxidation, and other reactions.
• Plasticizer Alcohols: A feedstock for producing C11 plasticizer alcohols through oxo synthesis processes.
