Description

Diisobutylene is a highly versatile and reactive branched-chain olefin, primarily a mixture of 2,4,4-trimethyl-1-pentene and 2,4,4-trimethyl-2-pentene. Its high reactivity and specific structure make it a crucial intermediate for synthesizing a wide range of high-value chemical products. This compound is essential for manufacturers in the petrochemical, polymer, and specialty chemical industries seeking to enhance product performance and develop new materials.

Application

• Chemical Intermediate: A key feedstock for the production of neo-acids (e.g., neopentanoic acid) and other specialty organic compounds.
• Polymer Industry: Used as a comonomer to modify the properties of polyethylene and other polymers, improving flexibility and impact resistance.
• Fuel & Lubricant Additives: Serves as a precursor for alkylate components in high-octane gasoline and as a building block for detergent additives in lubricants.
• Surfactant Synthesis: Reacted to produce alkylphenols and subsequently nonionic surfactants for industrial and household applications.
• Resin & Adhesive Production: Utilized in the manufacture of hydrocarbon resins, tackifiers, and adhesive formulations.
• Fine Chemical Synthesis: Acts as an alkylating agent in the synthesis of pharmaceuticals, agrochemicals, and fragrances.

Quality Control

Our Diisobutylene is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including gas chromatography (GC). A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We adhere to a robust quality management system to meet the exacting standards of our global B2B clientele.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 15-25°C.
