乙炔氢氯化均相催化反应动力学和机理的研究

A STUDY OF KINETICS AND MECHANISM OF HOMOGENEOUS CATALYTIC HYDROCHLO- RINATION OF ACETYLENE

本文研究了以HgCl_(2)为催化剂时乙炔氢氯化制氯乙烯均相反应的动力学。获得该反应速率方程为:r=k′[HgCl_(2)][H+]^(3)[CH≡CH],表观活化能为13.6千卡/摩尔。根据实验结果提出了该催化反应的机理。

The kinetics of the reaction of acetylene hydrochlorination in hydrochloric acid with mercuric chloride(HgCl_(2))as catalyst has been studied. The results showed that rate equation could be expressed by r = k’ [HgCl_(2)] [H+]^(3) [CH = CH],and the apparent energy of activation obtained is E = 13.6Kcal/mol. A reaction mechanism was proposed.
