Description of key information
[1,3-phenylenebis(1-methylethylidene)]bis[tert-butyl] peroxide is an Organic Peroxide Type D and has a SADT of 80 ºC. |
[1,3-phenylenebis(1-methylethylidene)]bis[tert-butyl] peroxide is an off-white to yellow solid. |
The melting range of [1,3 -phenylenebis(1 -methylethylidene)]bis[tert-butyl] peroxide is between 41.5°C to 51.0°C at normal pressure. |
The relative density of [1,3-phenylenebis(1-methylethylidene)]bis[tert-butyl] peroxide is 1.042 at 20ºC. |
No boiling point is available because the peroxide decomposes before boiling (its Self Accelerating Decomposition Temperature (SADT) is around 80°C. |
Granulometry: Light microscopic examination showed a flake type granular product, no fibres were observed. The fraction < 100 µm of [1,3-phenylenebis(1-methylethylidene)]bis[tert-butyl] peroxide is 3.1% (m/m). The PSD(particle size distribution)-characteristics are : d10 is 22µm, d50 is 69µm and d90 is 132µm. |
The vapour pressure of [1,3-phenylenebis(1-methylethylidene)]bis[tert-butyl] peroxide seemsvery low(estimated by calculation at 0.0091 Pa at 25°C and measured at 0.00012 Pa at 20°C for related 25155-25-3). |
[1,3-phenylenebis(1-methylethylidene)]bis[tert-butyl] peroxide is considered as insoluble in water based on the water solubility of 0,04 mg/Lat 20°C for related 25155 -25 -3, |
[1,3-phenylenebis(1-methylethylidene)]bis[tert-butyl] peroxide is potentially bioaccumulable based on a calculated logKow value of 7,3. |
Flammability is an intrinsic hazard of organic peroxides. |
[1,3-phenylenebis(1 -methylethylidene)]bis[tert-butyl] peroxide is non explosive. |
The oxidising properties has not been evaluated (the substance is an organic peroxide). |
