In the temperature range 402–425 °C, propylene oxide in a toluene medium decomposes to form propionaldehyde (60–70%), acetone (14%), and free radicals (25%). The ratio of products is invarient with temperature, suggesting a common precursor to all three products. Propionaldehyde further decomposes into free radicals. The first order rate expression for propylene oxide disappearance is3.7 × 10 12 e −51900/RT s −1 .
