Tert-Butyl Perbenzoate (TBPB)
SINOBIO
2909190090
Tert-Butyl Perbenzoate (TBPB, CAS 614-45-9) is an organic peroxide with the chemical formula C₁₁H₁₄O₃. It is primarily used as a free radical initiator in polymerization reactions and resin curing. It is thermally unstable and must be stored at low temperatures and protected from shocks and friction. The following are its detailed specifications:
*Molecular Formula and Structure: C₁₁H₁₄O₃, containing peroxy bonds (-O-O-), belonging to the perbenzoate class.
*Physical State: Usually a colorless or pale yellow liquid, possibly existing in solvent solutions (such as ethanol or phthalates).
*Melting Point and Boiling Point: Melting point approximately 8-9℃, boiling point around 112℃ (decomposes).
*Density: Approximately 1.034 g/cm³ (25℃).
*Solubility: Insoluble in water, readily soluble in organic solvents.
*Thermal stability: The peroxide bond is sensitive to heat; above 60°C, it may self-decompose at an accelerated rate, potentially leading to combustion or explosion. The half-life is 10 hours at 124°C.
| Appearance | Colorless transparent liquid |
| UN NO | 3103 |
| CAS NO | 614-45-9 |
| Assay | 99%min |
| Color no. : Platinum-Cobalt | ≤80 |
| TBHP% | ≤0.2 |
| Moisture % | ≤0.2 |
| Hydrolyzed chlorine % | ≤0.01 |
| Free Acid(asC6H5COOH)% | ≤0.1 |
| Reactive oxygen% | ≥8.07% |
| Refractive index | 1.495-1.505 |
| Melting point | 8 |
| Flash point | 96 |
| SADT | 63 |
| Form | Liquid |
| Solubility | Insoluble in water |
| Application | Used as a medium temperature initiator of polymerization reactions (such as polystyrene, polyethylene, polyacrylic acid), curing agent of unsaturated polyester resin, and vulcanizing agent of silicone rubber. |
* In free radical polymerization (e.g., LDPE production), TBPB decomposes at 60-100℃ to generate free radicals, promoting the polymerization of monomers such as ethylene.
* Used in the manufacture of polymers such as PVC.
* As a crosslinking agent for unsaturated polyester resins, improving the material's hardness and heat resistance.
* Participates in organic synthesis reactions, such as oxidation processes.
Standard package: 25kgs Drum.
Sample is also avaliable, provide customized package for different quantity.
Delivery time: 7-15 working days after receiving your deposit or according to clients requirement.
Our advantages: exporting directly which obeys China Customs, with sufficient capacity, stable supply and rigid quality control.
