Reaction:   1,3-Dioxolane, 2-methyl- → CH₃CHO + CH₃CHO
Reaction order:   1
Temperature:   753 - 753 K
Rate expression:   6.03x10¹² [s^-1] e^{-265200 [J/mole]/RT}
Category: Theory
Data type:   Transition state theory
Pressure dependence:   Rate constant is high pressure limit
Comments:   Reaction potential energy surface was studied using quantum chemistry and rate constants were calculated using transition state theory. Several quantum chemical methods were used. The Arrhenius parameters quoted here were obtained with the MPW1PW91/6-31++G(d,p) method.
