Description

tert-Butyl Hydroperoxide (TBHP) is a versatile and highly reactive organic peroxide widely used as a radical initiator and oxidizing agent in industrial synthesis. Its controlled reactivity makes it a critical component for driving polymerization and oxidation reactions with high efficiency and selectivity. This compound is essential for manufacturers in the polymer, fine chemical, and pharmaceutical industries seeking reliable and scalable process chemistry solutions.

Application

• Polymerization Initiator: A key free-radical source for the production of polystyrene, polyethylene, acrylics, and other polymers.
• Epoxidation & Oxidation Reactions: Used in the synthesis of epoxy resins, propylene oxide, and for the selective oxidation of olefins and sulfides in fine chemical manufacturing.
• Acrylic Resin Production: Serves as a crucial initiator in the manufacture of acrylic resins for coatings, adhesives, and elastomers.
• Synthetic Rubber Manufacturing: Employed in the production of styrene-butadiene rubber (SBR) and other synthetic elastomers.
• Pharmaceutical Intermediates: Facilitates specific oxidation steps in the synthesis of active pharmaceutical ingredients (APIs).
• Crosslinking Agent: Used in the curing and crosslinking of unsaturated polyester resins and silicone rubbers.
• Bleaching & Pulping Aid: Applied in pulp and paper processes as a bleaching chemical and delignification agent.

Quality Control

Our tert-Butyl Hydroperoxide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, assay, and impurity profiles. Certificates of Analysis (COA) documenting key parameters such as assay (by iodometric titration), water content, and active oxygen value are provided to guarantee consistent performance and supply reliability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its nature as a strong oxidizer and highly volatile compound, it must be kept separate from reducing agents, acids, bases, metals, and organic materials. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use.
