Oxidation Reaction of Typical n-alkanes in Adiabatic Condition

摘要

To study the reaction kinetics of the additive for some energetic material, oxidation of two typical n-alkane at low temperature ( < 500 ℃) was studied by Accelerating Rate Calorimeter. Onset temperature of exothermal reaction, max rate of temperature rise and temperature of max rate of temperature rise of n-heptane and n-hexadecane were made sure. According to the heat release rate, the reaction paths to ignition of sample n-alkane were discussed. The reaction rate constant and activation energy of different paths of n-heptane and n-hexadecane were got.
