Half-Life Calculation
The reactivity of an organic peroxide is usually given by its half-life (t½) at various temperatures. For DTBP in chlorobenzene, half-life at other temperatures can be calculated using the following equations:
Formula 1: kd = A·e^(-Ea/RT)
Formula 2: t½ = (ln2)/kd
Where:
Ea = 153.46 kJ/mole
A = 4.20E+15 s⁻¹
R = 8.3142 J/mole·K
T = (273.15 + °C) K
Temperature (°C) Half-Life
164°C 0.1 hour
141°C 1 hour
121°C 10 hours
