ABSTRACT
The solution of Pd(Ⅱ)-Cu(Ⅱ) was used as a self-screened catalyst of liquid phase catalytic oxidation to remove phosphine. Mass transfer and reaction kinetics were studied in a double-stirred cell. The results indicated that the system was an interfacial instantaneous reaction. Gas-side and liquid-side mass transfer coefficient were 3.88×10-7 mol?(m2?Pa?s)-1 and 6.74×10-7 mol?(m2?Pa?s)-1 (303.15 K) respectively. The rate constants of the first-order reaction were over the order of 105 under the experiment temperatures. Ha number was 552.56, and practical enhancement factor was 593.63.
