Description

Tertiary-Butylhydroperoxide (TBHP) is a versatile organic peroxide widely recognized as a powerful oxidizing agent and free radical initiator. Its controlled reactivity makes it a critical component in industrial synthesis and polymer manufacturing processes. This high-purity chemical is essential for producers in the polymer, petrochemical, and fine chemical sectors seeking reliable and efficient oxidation or initiation reactions.

Application

• Polymerization Initiator: A key free-radical initiator for the production of polystyrene, polyethylene, and acrylic resins.
• Epoxidation Agent: Used in the Prilezhaev reaction for the synthesis of epoxides from olefins, a fundamental step in producing plasticizers and stabilizers.
• Synthetic Intermediate: Employed in the manufacture of organic peroxides, fragrances, and pharmaceutical intermediates.
• Crosslinking Agent: Facilitates the curing and crosslinking of unsaturated polyester resins in fiberglass and composite materials.
• Oxidation Reactions: Utilized as a selective oxidant in organic synthesis for converting alcohols to carbonyl compounds and sulfides to sulfoxides.
• Fuel Additive: Acts as a cetane improver in diesel fuels and an ignition promoter for diesel engines.

Quality Control

Our Tertiary-Butylhydroperoxide is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes comprehensive analytical testing, including assay by titration and impurity profiling, to meet exacting customer and industry specifications. Certificates of Analysis (COA) detailing all quality parameters are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Keep away from incompatible materials such as strong acids, bases, reducing agents, and metals. Due to its nature as a strong oxidizer, store separately from flammable and combustible materials. Recommended storage temperature is below 30°C (86°F).
