United Initiators TBPPI-75-AL tert-Butyl peroxypivalate 927-07-1

2023-10-11tbppi-75-al
Product Name: TBPPI-75-AL (tert-Butyl Perisuccinate) CAS Number: 927-07-1 Molar Mass: 174.2 g/mol Content: 75% tert-butyl peroxypivalate, dissolved in aliphatic hydrocarbons Structural Formula: H 3 C C O CH 3 CH 3 O C C CH 3 CH 3 O CH 3 Product Description:
  • A colorless, free-flowing liquid containing 75% tert-butyl peroxypivalate, stabilized with aliphatic hydrocarbons.
  • This branched aliphatic peroxide is commonly used as an initiator (radical source) for the polymerization of monomers such as ethylene, vinyl chloride, and vinyl acetate.
Technical Data:
  • Appearance: Colorless liquid
  • Peroxide Content: Approximately 75% (mass percentage)
  • Active oxygen content: approximately 6.88% (mass percentage)
  • Inhibitor: High-boiling-point aliphatic hydrocarbons
  • Density (20°C): approx. 0.85 g/cm³
  • Viscosity (20°C): approx. 1.7 mPa·s
  • Refractive index (20°C): approx. 1.414
  • Critical temperature (SADT): approx. 25°C
  • Low-Temperature Storage Stability: Remains liquid at temperatures below -15°C
  • Recommended storage temperature: -15°C to -5°C
  • Maximum shipping temperature: 0°C
  • Storage Stability (Activity): 3 months from the date of delivery
Half-life data:
  • 10 hours/1 hour/1 minute (0.1 m/benzene): 56/74/110°C
Applications:
  • Used in the polymerization of high-pressure ethylene, in combination with peroxides that offer higher thermal stability. The applicable temperature range is 130–190°C.
  • Characteristics: Highly effective, liquid form, and easily miscible with high-boiling-point aliphatic hydrocarbons.
  • For vinyl chloride, it can be used in bulk or suspension polymerization; the applicable temperature range is 50–65°C. Dosage: 0.04–0.1% as supplied.
  • Suitable for the polymerization of other monomers, such as acrylonitrile, (meth)acrylates, and vinyl acetate, with an operating temperature range of 50–80°C. Dosage: 0.04–0.1% as supplied. Use in combination with peroxides that offer higher thermal stability to reduce residual monomer content in the polymer.
Standard packaging:
  • 25-kilogram high-density polyethylene drums
