- CH-70-AL is a colorless liquid consisting primarily of approximately 70% 1,1-di-tert-butylperoxycyclohexane, which has been desensitized using a fatty solvent.
- This cyclohexanecarbonyl cyclopropanone ether compound is used as a free-radical initiator for the polymerization of monomers (e.g., styrene).
- Appearance: Colorless liquid.
- Desensitizing Agent: Fatty solvent.
- Molecular weight: 260.4 g/mol.
- Content: Approximately 70% w/w.
- Active Oxygen (AO): Approximately 8.60% w/w.
- Density (20°C): approximately 0.88 g/cm³.
- Viscosity (20°C): approximately 4.8 mPa·s.
- Flash point: approximately 55°C.
- Explosion hazard temperature: approximately 60°C.
- Cold Storage Stability: Below -20°C.
- Recommended storage temperature: below 30°C.
- Shelf life from date of delivery: 6 months.
- Standard packaging: 17-kilogram HDPE plastic drums.
- Used as a polymerization initiator for styrene.
- Temperature range: 100–140°C.
- Usage level: 0.02–0.1% (as is).
- Special Advantages: Reduces residual monomer content; does not react with chain modifiers (e.g., mercaptan alcohols); does not undergo hydrolysis in alkaline media.
- Recommended for use in combination with more reactive peroxides (e.g., tert-butylperoxy 2-ethylhexanoate).
- Potentially detectable decomposition products: acetone, tert-butanol, hexanone.
- Avoid all sources of heat, light, and moisture, and protect the product from contamination by impurities.
- Store within the safe temperature range.
