Description

Tetraisobutylene is a high-purity, branched C16 olefin derived from the dimerization of isobutylene. This specialty chemical serves as a crucial intermediate and building block in the synthesis of high-performance additives and functional fluids. It is primarily utilized by manufacturers in the lubricant, fuel additive, and polymer industries seeking to enhance product properties such as thermal stability and viscosity index.

Application

• Lubricant Additive Intermediate: A key raw material for producing succinimide dispersants and other ashless additives that keep engines clean and improve oil life.
• Fuel Additive Synthesis: Used in manufacturing detergents and stabilizers that prevent deposit formation in gasoline and diesel fuel systems.
• Polymer Modification: Acts as a comonomer or chain transfer agent to modify the properties of polyalphaolefins (PAOs) and other specialty polymers.
• Chemical Intermediate: Serves as a versatile precursor in organic synthesis for producing surfactants, corrosion inhibitors, and specialty chemicals.
• High-Performance Fluids: A component in the formulation of synthetic base stocks and functional fluids requiring excellent oxidative stability and low-temperature performance.
