Standard enthalpy changes of the initial pyrolysis process of ethylbenzene were computed by five methods (UAM1, UHF/3-21G*, UB3LYP/3-21G* and UB3LYP/6-31G*). UB3LYP/6-31G* due to its accuracy compared to the experimental values was chosen to calculate the thermodynamic and kinetic parameters of the process at different temperature ranges (298 ~ 1573 K). The computation results showed that ethylbenzene began to pyrolyze at 973 K and the main product was styrene.
