Description

Triisobutylene is a branched-chain olefin primarily composed of trimers of isobutylene. This compound matters as a versatile chemical intermediate valued for its reactivity and utility in synthesizing higher-value derivatives. It is needed by manufacturers in the petrochemical, lubricant, and specialty chemical industries for producing additives, surfactants, and other functional materials.

Application

• Key intermediate in the production of lubricant and fuel additives, such as polyisobutenyl succinic anhydride (PIBSA).
• Raw material for manufacturing alkylphenols and other surfactants used in industrial formulations.
• Component in the synthesis of plasticizers and specialty polymers.
• Used in organic synthesis to create fine chemicals and pharmaceutical intermediates.
• Starting material for producing neo-acids and other high-performance chemical derivatives.
• Employed in research and development for novel catalytic processes and material science.

Quality Control

Our Triisobutylene undergoes rigorous quality testing to ensure compliance with industry standards and customer specifications. We maintain strict batch-to-batch consistency through advanced analytical techniques. Certificates of Analysis (COA) detailing purity, composition, and physical properties are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Due to its nature as an easily oxidized organic compound, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep container tightly sealed when not in use to prevent evaporation and contamination.
