| Abstract: | The kinetics of the reaction of acetylene hydrochlorination in hydro-chloric acid with the complex catalyst HgCl3-BiCl3 has been studied.The results showed that the rate equation of the reaction could be expressed by r=(k+k'BiCl3]/H+])HgCl2]·H+]3CH≡CH] with k= 0.00239, k' =0.0269 (at 25℃). Areaction mechanism which includes two parallel reactions composed of some complicated concecutive reactions was proposed. The Corresponding apparent energies of activation are 13,4 Kcal/mol and 14.8 Kcal/mol. |
