【摘要】 本文研究了在HgCl₂-BiCl₃复合催化剂作用下,乙炔氢氯化制氯乙烯均相催化反应的动力学,获得该反应速率方程为:r=（k+k’[BiCl₃]/[H^-]）[HgCl₂]·[H⁺]³[CH=CH].在25℃时k=0.00239,k’=0.0269,根据实验结果,提出了由两个复杂的连串反应组成的平行反应机理,相应的表观活化能为13.4Kcal/mol及14.8Kcal/mol.更多还原

【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 bywith k= 0.00239, k’ =0.0269 (at 25℃). A reaction 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.更多还原
