• Perodox® 22 - 1,1-Di(tert-butylperoxy) cyclohexane

    CAS: 3006-86-8

    High-Purity Organic Peroxide | Polymerization Initiator & Crosslinking Agent

  • Product Overview

    Perodox® 22, also known as 1,1-Di(tert-butylperoxy)cyclohexane (CAS Registry Number 3006-86-8) is a high-purity, dialkyl organic peroxide. It is a clear, colorless to pale yellow liquid, widely recognized for its effectiveness as a free radical initiator and crosslinking agent in polymer chemistry.

    This compound features two tert-butylperoxy groups attached to a single carbon atom of a cyclohexane ring, giving it a unique decomposition profile. Its symmetrical structure contributes to its stability under storage conditions and predictable decomposition kinetics at elevated temperatures, making it a preferred choice for controlled polymerization and crosslinking processes in industrial applications.

    Molecular Weight: 260.4

    EINECS Number:221-111-2

  • Applications

    The primary utility of 1,1-Di(tert-butylperoxy)cyclohexane stems from its ability to generate tert-butoxy radicals upon thermal decomposition.

    These radicals are highly effective in initiating chain-growth polymerizations and forming crosslinks between polymer chains.

    Polymerization Initiator

    Used in the high-pressure free-radical polymerization of ethylene to produce

    Low-Density Polyethylene (LDPE). It also serves as an initiator for the polymerization of styrene, vinyl chloride, and (meth)acrylates.

    Crosslinking Agent (Curing Agent)

    Critical for crosslinking (curing) saturated and unsaturated polymers like

    polyethylene (PE),ethylene-propylene-diene monomer (EPDM) rubber

    , and silicone elastomers to enhance thermal, chemical, and mechanical properties.

    Organic Synthesis

    Employed as a radical source in organic synthesis for oxidation reactions and C-H functionalization under thermal conditions.

    Composite Materials

    Used in the manufacture of fiber-reinforced plastics and composites, where it initiates the curing of resin systems.
