Description

Dicetyl Peroxydicarbonate (CAS 26322-14-5) is a high-purity organic peroxide with the molecular formula C₃₄H₆₆O₆, widely utilized as a radical initiator in polymerization reactions. This compound, also known by its IUPAC name hexadecoxycarbonyloxy hexadecyl carbonate, is characterized by its stability under controlled conditions and its effectiveness in initiating free-radical processes. Available as a white crystalline powder or as a suspension in water (e.g., Perkadox 24W40), it is commonly employed in the synthesis of polymers, including PVC and other vinyl-based resins. Proper storage at low temperatures is essential to maintain its reactivity and shelf life. Suitable for industrial and research applications, this peroxydicarbonate derivative is handled with strict safety protocols due to its thermal sensitivity.

Application

Dicetyl Peroxydicarbonate serves as a highly efficient initiator for polymerization reactions, particularly in the production of polyvinyl chloride (PVC) and other vinyl polymers. Its controlled decomposition at elevated temperatures enables precise radical generation, ensuring consistent polymer chain formation. The compound is favored in emulsion and suspension polymerization systems due to its solubility characteristics. It is also used in specialty polymer formulations requiring low-temperature initiation. Strict temperature control is necessary during handling to prevent premature decomposition.
