|Abstract:||The kinetics of the gas-phase butadiene+2HI=buttne+I_2 has been studied from 180° to 230℃ using a photometric procedure. It is shown that the reaction mechanisms of the addition reaction of HI to butadiene consist of the following two steps. C_4H_6+HI→^^kC_4H_7I (slow), C_4H_7I+HI→C_4H_8+I_2 (fast). The second-order rate constant k is given by (units of l/mole-sec), log k=8.59-18.3/4.575T. The small activation energy of the addition reaction predicts that the -CH=CH_2 of butadiene exerts very interesting influence on the addition reaction rate.|
