Description

Butene CAS NO 25167-67-3 is a versatile, highly reactive hydrocarbon gas belonging to the alkene family, primarily used as a crucial building block in petrochemical synthesis. Its value lies in its ability to undergo polymerization and alkylation reactions, forming the backbone of numerous high-volume industrial materials. This product is essential for manufacturers in the plastics, synthetic rubber, and fuel additive sectors seeking a reliable and consistent feedstock.

Application

• Polymer Production: A key monomer for the manufacture of polybutene and as a co-monomer in the production of linear low-density polyethylene (LLDPE) and other polyolefins.
• Chemical Intermediate: Used in the synthesis of butylene oxide, butanediol, and other valuable derivatives for solvents, plasticizers, and fine chemicals.
• Fuel & Lubricant Additives: Serves as a feedstock for producing alkylates and other components that enhance octane ratings in gasoline and improve the performance of lubricating oils.
• Synthetic Rubber: Employed in the production of butyl rubber (IIR), which is critical for tire inner liners and other sealing applications due to its excellent impermeability.
• Industrial Fuels: Can be used as a component in liquefied petroleum gas (LPG) and as a high-energy fuel for specialized industrial processes.
